In this second week of veg I started adding some nutrients to the plant water. (below the recommended doses) 🔥 Since they are growing well next week I will try to apply the manifold , hoping to be able to increase the final yield of this genetics that I love. ✂️🌱

The ladies are looking nice very healthy the one that broke came back and sprouted like crazy took 3 cuts off since I didn't want those to reach first time who knows what will happen free 3 cuts

Sprouted in 24hrs, directly into soil with the sprayer mixed light with velokelp.

Entering a new week :) Some lower leaf yellowing but overall very healthy. I wonder what to expect in terms of bud growth since this is my first time growing a regular plant. I'll have my microscope ready to check tricohomes in a few weeks Any comments or insights are always welcome Will probably post more photos later this week I'm happy with my CMH lamp. I don't want to give my plants a gimmicky light spectrum in flower

8/1 Took another video but didn't upload either videos when I was in town. I'll have to upload later. I have a lot going on and I need to consult my diary more often. The Temps dramatically changed. I watered yesterday just a few that were light but then it poured all night. This morning things looked SUBSTANTIALLY better. I think as long as I can get some sunlight the next few days things will be alright. That streak of weather in the 100s really did a number on me and my plants. Everytime I go they seem to be looking better so I hope that they bounce back and I don't lose anything after all this work. Plants seem "strong" though. They appear very healthy. This just seems like a mistake I made that was substantially worsened by severe thunder storms we weren't supposed to get. If they don't come back before rain I may move the plants that haven't recovered yet inside the barn for the night. It really depends. I want them to dry out. I'm thinking of going and putting a fan in the cage on the smart pots. I just need to keep an eye on them. UPDATE: I was worriedly watching my plants from the cams and got a message from my father saying my plants were "REALLY DROOPY." I got there and noticed they were WAY worse then earlier and it was sunny and 70's. I got my dude on the phone and sent him several pictures. Luckily I had a second opinion also from my father. A 3cu ft bag of 707 is 22 gallons. These pots were light like that. They just have a seven foot plant in them lol. I'm so happy. I was planning on bringing them Inside tonight in case of ANY rain, luckily I was able to ascertain THE REAL problem, consult my diary and askother growers. Things are looking good. I'm so happy I'm not overwatered. 8/2 Thank the Lord! And my father for his constant vigilance and my commercial buddy for always being there for me. I went over this morning and everything is back up. Plants definitely got stressed though. I think I was OVER and UNDER watering during those days where it was 100 degrees. It'd 68 today. I say this because as soon as I watered the plants they started picking right back up. Luckily I had a dry bag of 707 to pick up and compare with my 20 gallon grow bags and had my father check the weight as well. He's a forester and told me the weight was about tge same. I gave the big blue cheese in the back closer to 2 gallons until I saw some water coming out the bottom. The reason I think I may have overwatered is that the water evaporated as i had watered during the day or at night but not the 10% that they needed. I didn't QUITEgive them all their 10% last time more like I split the difference and did a gallon amd half. Some did get two though. I noticed some light yellowing going up one of the plants that I've watered the most. These plants are transitioning fast to flower. I think I've got the watering schedule down better and that's "don't water them on a schedule". I'll have to individually take note of the plants. Also on that plant and a few others I see minor nute deficiencies so as soon as I can feed I'm going too. I'm going to show my buddy all my info and ask his advice before i take the next step though. I can't believe they made it through this. Talk about anxiety. Wow. UPDATE: Talked to my commercial buddy. He advised to pick off any of the dead leaves, (which I mostly already have there weren't many) and to wait until next water to feed. He broke it all down in a way i could understand. Then he broke the feeding down further for me so I now know where to start. He did say he thinks my only problem this year will be, "finding a place to store it" lol. I thought he was joking but he went out back and brought out five gallon buckets with screw top lids lol. This back and forth dialogue (with a professional) is seriously lowering my anxiety and giving me confidence that im doing the right thing. Hes never led my wrong and hes always been there. So has my dad. He said to take the old man out for coffee because he saved my ass! I opted for the bottle of whiskey instead. I'll be checking them later. I'm waiting to feed until next watering and I'm waiting to apply BT. I don't want to do anything to a plant that has been that stressed. I'm giving them a few days to chill. Then the twenties will get a quart of grow big, big bloom and calmag and I'll convert that measure to the same amount for the 30's, and 50's. I'm not sure EXACTLY how big that tote is but I think it's closet to 30 than to 40. So I've got a solid plan for the week. I think what I'll be looking to do next is get my supports up. The wind has been crazy but these plants (even when stressed) seemed super strong! Still no fungal stuff knock on wood. UPDATE: Had to take the car to the mechanic and snag my wheeler to make it home. I sefoliated quite a few bog yellow fan leaves and some smaller leaves down low. Plants went through some stress thats for sure. I HAD to leave my phone with the wife as she had a telehealth appointment so I couldn't take pictures. I wish I could've because things are looking great. I can't wait until things dry out a bit and I can feed! I'm STILL in awe of how my plants look RIGHT NOW and how the looked yesterday. Another buddy said If I didn't see it (and I didnt know you) I wouldn't have believed it was even the same garden! I'll check AGAIN later if my car is ready. I'm anxious to feed and get my supports up. Plants are STRONG though. 8/3 Plants looked great this morning. I did notice what looked like nute deficiencies on the plants I've watered most. After speaking with a few local growers I decided to water. I watered everything a gallon. The containers got more. The 10 got less. Then i mixed up a feeding solution of 1 tsp grow big 2 big bloom and .5 calmag and fed the 20s approx 1.5 pints. A little less for the 10 and a little more for the bigger pots. I'm going to go back over and if I see no negative effects from earlier I'll use the rest of the solution. I'm hoping this was the right decision. It hasn't been enough time but the bags were light. Not SUPER light but last time I waited it didn't work out well for me. Two local growers have told me theyve been watering daily and they have plants in raised beds and right in the ground. I want my watering to be in the morning anyway. Hopefully this works out. I'll update. UPDATE: Went back over and everything was standing up nice. They loved that water and the small dose of nures hasn't burned them so ill be able to use more next time. I used a Gatorade bottle thats 1.25 pints amd went from there. A total of two gallons was used on the garden. Things look amazing. Things are changing on the daily. I'm losing some leaves now. Well they aren't dropping off but I'm plucking them before they yet that far. I need to water in larger volumes I think. Plants are drying out too quick. Others are saying they are watering much more often as well. It really hasn't been raining and these plants are huge. I have lush green leaves but this transition and the added watering I think has leeched a lot of the nutrients from the soil. Since I have the fox farm that's what I'll be using. I still have a couple leaves that are destroyed by a fourkined plant bug. It's very identifiable so theres another I need to find. Also seeing chunks missing from leaves. I need to up my ipm game. I don't want to do more than one thing at a time though so I know what happened if anything goes wrong. Since i did the nutes today the spraying of BT or captain Jack's I'd going to have to wait. Despite losing these old fan leaves my plants are dense. Defoliating really helped with airflow. I also noticed some chlorosis on a few leaves. That's why I'm going to start doing the 10% minimum. I'm waiting until they are real dry then I'll give everyone (but big blue) their 10%. I got run off from big blue just from like a gallon amd a half today. I hope my 2 minute video uploaded. It says it dis but u bet it didn't. I'm trying again and I'm at 12%. Let's see if my patience lasts. Looks like it doesn't want to upload 8/4 Thunderstorms and heavy rain all night. It's supposed to rain steadily all day. Plants werent drooped or blown around looking or anything after this storm and I only have minimal supports up. I defoliated anything that needed it. Just a few yellow leaves on the bottom interior. More like nitrogen deficiency. I am watering to frequently though. Im noticing some chlorosis (minor) on old far leaves. Could just be that the soil is getting depleted but "if the brown surrounds your plant is drowned" and I noticed a few leaves like that. Just a couple bit i know what to look for. I hate to say it but i think ive almost got things dialed in for this grow. I will need to put up further supports. These are some STRONG plants. I shook them all off today. The seemed to love the nutes. Plants looked way better this morning than I was expecting. I need to up my watering volume to 10% everytime. I DID fine more pillar damage when defoliating and a four lined plant bug mark on the purple punch in the ten. 8/5 It's not raining right now but it Rained all day and night. Plants really seemed to likecthise nutes. I'll up it to a quart next feed. I defoliated what needed it. Found my FIRST totally yellow leaf of the season. Big old interior leaf i must've missed earlier. Smell has greatly increased. Seeing that these plants seem to have no ill effect from all this water I feel more confident about my ability to fully water them their 10%. Especially since they are massive plants. I have one daln near 8ft and it's damn near as wide. Real good airflow. I think this is gonna be my year. I certainly hope so. I need to get rid of that fourlined plant big but more importantly I need to deal with pillars proactively so next nice night I'm going to treat with bt. Super proud of myself so far. 8/6 Didn't rain much yesterday. In fact I stepped out my door and the sun was fully visible and bright while rain poured down around me. It wad a cool experience but the plants dodnt get much for water. I checked the weight this morning (heavy) and shook off the plants and did my normal morning inspection. I news to remove a pallet so I have more room. Plants are really trying to flower. Next week I'm gonna yet them with a stronger dose of nutes. Last year this was about the time I lost my crop. Knock on wood but this is the healthiest crop I've ever had. I MAY apply BT tonight. Haven't decided yet. I'll keep the diary updated. UPDATE: Went over to check the plants that were WET and HEAVY this MORNING because of the windstorm. If dried the bags out completely. Everything but the 10 was drooping right over like before. Good thing I've got some pretty good intuition. I took two videos. I gave everything their 10% 2 gallons each and for each container plant. Plants were back up by the time I was done adding supports. 8/7 Sunny this morning. Plants looked good. Had to defoliate some dead leaves. I can't believe those grow bags dried out so fast yesterday! Its just the wind was so strong! Plants were right sideways! They got some syrong roots thats for sure. One of them (my canary) seemed light this morning! But we are getting an inch and a half of rain starting tonight into tomorrow so im not watering ANYTHING. I'm not sure what I'm going to do IF anything. I added to my supports. I COULD put EVERYTHING in the barn where we put heavy equipment. I'll probably at least bring a couple inside in case something horrible happens. Things arecreally doing good. Flowering up nice. Found a cicada on one yesterday. First time I've ever seen one. I'll update with what I decide to do. UPDATE. My canary seems a little light and is losing lots more leaves im not sure if it's because of the transition to flower but I assume that has something to do with it. Plants still have MORE than enough leaves. Found a couple pillars and killed them. Took a video. I have one blueberry cheese that I hope doesn't have a fungal infection as it's losing more leaves. But it takes more water and is greener and fuller up top. I think I'm just worried because of last year. I've done what I can gor the storm so let's see what happens if I NOTICE it get too bad I can bring some indoors.

Day 36 I guess I can call it bloom. Nice strong pistils shooting all over. She is the tallest so far making me raise my lights a little more. Day 38 Now Californian Snow is the tallest :) Ztrawberry stopped at a perfect height, it looks like she's gonna develop into a beautiful lady. Fat white pistils all over 😻 Day 39 Happy girl got 2500ml cm bg bb bh 6.3ph ~1EC She is perfect, symmetrical, stopped stretching at about 50cm, flowers are mostly leveled, branches are strong, leaves point up unless I water. I think she's also turning purple. Beaut 😻 Day 42 I think I saw some burnt tips but she still looks super happy and healthy. The most vigorous plant I've had.

Week 02 Introduction This week has been a bit of a struggle. Had my first experience dealing with slime and brown algae. But I think adding enzymes and increasing the beneficial bacteria helped to fix the issue. Also experienced nutrient burn for the first time. My nutrient solution strength got as high as 671 PPMs. So backed it down to about 430 PPMs during the end-of-week reservoir change. Also cut Hydroguard (expired?), CaliMagic, and Superthrive from this grow. Now she's still stunted, but is starting to recover. Hopefully... [START OF WEEK 02] Day 01 - Monday - 08/10/20 - Total Days: 008 ----------------------------------- - [0830]: Still looks a bit yellow. But getting larger! --- Solution strength was at 248 PPMs. --- Just topped off with a bit of distilled water --- PH went up to 6.1 so PH'd down to 5.8 --- Ran the top feed for a bit to wet the hydroton. - [2130]: She's looking even more yellow now. --- Even the new leaves are really yellow. --- Decided to add more base nutes. --- Added 4ml of Sensi A --- Added 4ml of Sensi B --- Now at about --- Solution Strength went up to 304 PPM. --- PH was at 6, --- Also raised the water level a bit more. --- I really hope it's a nutrient deficiency and not an over-watering issue. --- Please live! Day 02 - Tuesday - 08/11/20 - Total Days: 009 ----------------------------------- - [0830]: Looking less droopy. But still yellow. --- Decided to do a reservoir change. --- 4.5gal of distilled water --- 8ml of Sensi Grow A --- 8ml of Sensi Grow B --- 8ml of Voodoo Juice --- 4ml of B-52 --- 4ml of CaliMagic --- 4ml of Hydroguard --- 4 drops of Superthrive --- PH'd down to 5.8 --- Solution strength: 302 PPM --- Since I didn't want to risk over-watering the rockwool, I did not to do a top feed, may do one tonight after the sleep cycle (lights are still set to go off at 10am and back on at 4pm). --- As I was doing a reservoir change, I noticed that the tubes and bucket were a bit slimy. Didn't really stink or anything. Is this normal? Maybe due to the Hydroguard and Voodoo Juice? --- I hope she gets better soon! - [2215]: Getting larger! But still yellow. --- Also can see a root growing through the net pot! Tiny little thing but it's there! Will have to start dropping water once more appear. --- After looking over a few DWC diaries using AN nutes, seems like my solution strength is still too low. Most around this stage average around 500 PPMs with about 4ml per gallon. --- Top fed for a minute to wet the top of the hydroton. --- Solution strength went down to 263 PPM. --- Added 8ml more of Sensi A --- Added 8ml more of Sensi B --- Now base nutes are at 16ml for 4.5 gal of water. --- PPMs went up to 411. --- Still lower than 500 PPMs, but that's okay. --- PH was at 6. Not sure if I should adjust PH using AN nutes. So going to not ajdust unless PH goes above 6.1. Day 03 - Wednesday - 08/12/20 - Total Days: 010 ----------------------------------- - [0830]: Looks like more root growth! --- She still looks yellow. But leaves are perky. --- PH was at 6.2 so lowered down to 5.8. --- Solution strength was at 394 PPMs --- Since roots are still growing, I decide to lower the water level a bit. Now water level is a bit below the net pot. - [2200]: Root is getting longer! --- Slime is returning. Not sure why. --- Solution strength: 357 PPMs --- PH: 6.1 --- Decided to add an enzyme along with more beneficial bacteria to hopefully cure the slime. --- Added 16ml of Sensizym --- Added 5ml of Hydroguard --- Added 8ml of Voodoo Juice --- New solution strength: 430 PPMs --- New PH: 6.1 --- Top fed for a minute. --- This slimy residue is really freaking me out! I hope the added enzymes will help eliminate the slime. --- Going to do a full reservoir sterilization/nutrient change over the weekend. Please survive until then girl! Day 04 - Thursday - 08/13/20 - Total Days: 011 ----------------------------------- - [0930]: I think the enzymes worked! There is little to no slime now! --- Although I think the root was also dissolved in the process. It's now just a little stub sticking just below the net pot. The enzyme is also suppose to dissolved dead roots too but guess that root was too weak? Not sure what happened there. But I think the slime is cured! --- Solution strength went down to 395 PPMs. Decided to add more base nutrients. --- Added 8ml of Sensi A --- Added 8ml of Sensi B --- Added 4ml of B-52 --- Solution strength went up to 598 PPMs. --- PH was at 6.1 --- As long as the PH is between 5.5 and 6.3, I'm not going to use PH Up or Down. But still will monitor PH levels. - [1715]: Checked up on her after her nap and shes looking alive but stunted. But no slime! --- Decided to add some sugars to help maintain the enzymes and beneficial bacteria. --- Solution strength was at 587 PPMs. --- PH was at 6.2 --- Added 8ml of Bud Candy --- Solution strength went up to 671 PPMs. --- PH also went up to 6.3 --- Lowered water level a bit to hopefully promote more root growth. --- Top fed for a minute. --- She is getting bigger, but still looks yellow. Day 05 - Friday - 08/14/20 - Total Days: 012 ----------------------------------- - [0915]: Leaves look a little burnt on the tips. Still no slime. --- Going to back off on the PPMs to hopefully fix the nutrient toxicity. --- Solution strength was at 632 PPMs --- PH was at 6.3 --- Added/Removed water until PPMs were at 536. --- PH was still at 6.3 --- Raised water up a bit, then top fed for a minute. - [2200]: Looking better. Still yellow though. --- Solution strength: 514 PPMs --- PH: 6.5 --- Added PH down. --- New solution strength: 518 PPMs --- New PH: 5.2 --- PH was kind of high. So decided to PH down. Had to use quite a bit to bring it down. But eventually got it to drop down to 5.3. A little low, but so far, the PH has always gone up so wanted to start it really low. --- Ran the top feed for a minute to re-saturate the top of the hydroton. Day 06 - Saturday - 08/15/20 - Total Days: 013 ----------------------------------- - [0830]: She looks stunted. leaves are still yellow. --- Solution strength: 514 PPMs --- PH: 5.6 --- Top fed for a minute. --- Not sure what to do at this point. Going to do another reservoir change soon. Hoping she lives until then. - [2145]: Looking pretty much the same. --- A bit of slime has returned. Since I've been diluting the nutrient solution, the enzyme ratio has dropped. So I guess this is expected. --- Also noticed that slime build up was on the air-stones. Never really checked the stones so not sure how long that has been there. Looks brown too, which can't be good. --- Going to do an H202 sterilization of the system (minus the net pot) tomorrow so did not add anything. --- Lowered the water level to below the net pot. --- Then top fed for a minute. Day 07 - Sunday - 08/16/20 - Total Days: 014 ----------------------------------- - [0900]: STERILIZATION DAY! --- Decided to skip today's night cycle for a deep clean. --- I'm hoping that skipping a night cycle won't be too stressful. --- Temporarily moved her to a new bucket. --- Used about a half of gallon of straight distilled water to flush out the net pot. --- Drained the system and wiped up all the brown sludge. Also removed the air stones and cleaned up all the goo. --- Filled the system with 2 gallons of distilled water and at least 30ml of food grade hydrogen peroxide (35% strength). --- Yea its a lot, but since I'm not going to sterilize the system overnight, I went with a really high doseage. Basically I kept adding until I started to see little bubbles start to form. --- Then I ran the water pump. - [0915]: Boiled the air stones in tap water for about 10 min. Then reconnected them to the airlines. --- I let the air stones and hose soak in the sterilization solution for about 5 minutes so the peroxide can absorb into the stones. Then ran the air stone to help mix and agitate the solution. --- Occasionally, I'd repeat the process of turning the air pump off for a few minutes to let the stones soak. - [1000]: Covered the top two row of holes of the net pot with some aluminum tape. Hopefully this solves the light leaking in through the hydroton. - [1200]: Used an old toothbrush and scrubbed the pump clean. Then drained the system. --- Refilled with more distilled water and peroxide. Again added a lot. --- Ran system again to sterilize even more. - [1530]: Drained the system and refilled with distilled water to rinse. --- Ran the system for a few minutes, then drained and rinsed again. --- Did this a few more times over about an hour. - [1630]: Added 4 gallons of fresh distilled water. --- Added 15ml Sensi Grow A --- Added 15ml Sensi Grow B --- Added 12ml of B-52 --- Added 16ml of Voodoo Juice --- Added 16ml Sensizym --- Solution strength was at 430 PPMs --- PH was at 5.6 --- I was going to add Hydroguard, but I think the bottle is expired. Since 2017 or 2018!? I think Hydroguard is good for up to 2 years from the date on the bottle or 6 months after opening. So not going to use from now on. I wonder if this could have contributed to the slime build up. --- Also removed the CaliMagic and Superthrive too. Going to only use AN products to eliminate the chance of incompatible nutrients. --- Placed her back in the bucket and top fed for a minute. --- Here's hoping for the best. Going to let it ride until morning! Please feel better! [END OF WEEK 02]

These photos were taking yesterday and I meant to post than but here we are. They seem to be doing well, growth seems to be picking up a bit but I've noticed slight burns and I think I just started nutrients a little bit too early. A new addition to the tent is a 4th seed I planted today, I'm goign to breed the best female and male, hopefully I get two females and one male but well see.

After topping last week we've just been watching them grow. Bending down the branches to help them spread out. Over this next week I'll start my lst ties to help pull them down and out.

Buenas noches familia, sorpresa, jueves noche por aquí , actualizamos las power plant xL. Es la última semana antes de nuestra cosecha, el tiempo se nos echó encima y las Flores ya están echas, se preparó un lavado de raíces y tijeretazo,para sucesivamente colgarlas.( PRIMERA VEZ que se me echa el tiempo encima con la floración, jurao) Me habría gustado darles algo de estrés hídrico, pero lo veremos con las lemon kush y las northern light xL. -power plant xL es una cepa con predominancia sativa, con una corta floración,es un ejemplar fácil de cultivar, fuerte, y vigoroso. Estos ejemplares se cultivaron en 7L en sustrato light MIX de plagrOn, controlando en todo momento el PH de nuestras plantas, y dándoles de comer una gama advanced nutrients bastante básica. -PROS: facil cultivar, flores llenas de resina , flores compactas, ramas laterales largas. -CONTRAS: hay que tutorar por el peso de la flor, floración demasiado rápida a mi gusto (no te das ni cuenta). *Aquí ya me despido hasta la cosecha familia.

First full week of flowering with some more training and defoliation. Both plants received 2 litres this week. I believe that was too much because leaves were droopy for much of the week. I'm going to let them dry for 6 days and then will start with Bloom nutrients. I'm also surprised by how different these plants look seeing as they're the same strain.

▶️ -Muy frondosas;ocuparon practicamente todo el espacio del armario. -Yá puestas a fotoperiodo 12/12,las dí la segunda aplicación Delta9,esta vez via riego;la tercera y ultima será dentro de 10 dias. 🐭🐭

Excelente experiencia, volvería a cultivarla nuevamente.

Day 33-40 (May 24th-May 31st) (Day 34) I just found a herm branch on the tight blueberry pheno. It looks like a random pollen sack opened right above a lower branch. I removed the sack but I saw a small amount of dust fall onto one of the lower branches. I’m going to leave it to see if it will pollinate that small branch at all. I spent a good 5 minutes looking closely for bananas or claws but couldn’t find anymore. The main bud is clearly unaffected so I will just leave it unless it is visibly seeding itself. Too bad because I’m really excited for this plant. (Day 36) Not a lot has happened since I flushed them. Growth actually looks healthy and I don’t see any deficiencies on anything yet. (Day 37) Both of these badazz cheese phenos are picture perfect and easily hold up against Canadian and California quad grade. I might try to reveg them at the end and take some clones. They have this unique pungent, grassy, sour milk smell that is just wonderful. The density and bud structure is looking great too. This whole plant will probably take 3 minutes to trim if that. (Day 38) Just found a banana on the shitty blueberry pheno. This pheno is trash and I would honestly throw it away if it didn’t mess up the 3 perfect rows. It has almost no frost, no smell, is airy and has bad structure. I’ve actually never seen a plant with such little frost. Even outdoors. (Day 39) I think most of this tent will be done by day 60 but I will probably ride it out until day 70+. I don’t think the blueberries or the jacks will fill out very much either way but taking it too day 70 will ensure maximum production from each plant.

She's looking super healthy and and strong can't wait to see this beautiful strain in full flowering stage, I'm feeling a very good stretch,shed definitely a big girl,she's eating very well, no deficientes or nutrients burn so far. Let's see how this wonderful organic lady performs. On August 9th I start to see the change from vegetative stage to flowering stage,she looks super healthy and strong,I missed some watering a few days ago,however she is perfectly fine and happy,she's a dream to grow.

Hola, las plantas estan espectaculares, la prefloración va perfecta, supongo que la próxima semana empezaran a engordar y formar racimos, tengo pensado aplicar el rippen y floraklen para la semana 7 y 8 y luego 72 hrs de oscuridad y cosecha. A ver si todo sigue adelante sin problemas. Saludos a todos y buenos humos

good week! she continued to grow and she started to put up those white hairs!! flower is comming babyyy
