As you can see she is in full flowering mode right now. She has slowed down the vertical growth and I can see “hairs” everywhere. During this week I took off some fan leaves as advised by the breeder and I will probably do it again in week 5 of flowering. Despite feeding her with solid dosages of BAC nutrients some of the lower leaves have turned a bit yellow so I will increase the amount of “food” she gets from now on. I have ramped up the power on the Bilberry lamp to 80%. I must say this lamp is out of this world. I hope the end product will reflect it. Hope she keeps going good.

Que pasa familia, actualizamos 3 semana de floración de las Original de la web de GrowBarato Van progresando bien las flores , lastima no tener algo más de watios en este armario. Tienen un buen color , se ve que no llevan carencias. En una semana o 2 seguramente pueda pasar algún ejemplar alguna otra carpa y darles algo más de espacio. Agrobeta: https://www.agrobeta.com/agrobetatiendaonline/36-abonos-canamo Mars hydro: Code discount: EL420 https://www.mars-hydro.com/ Las maximas de temperatura no superan los 26 grados y las mínimas no bajan 20, así que no me puedo quejar. Los niveles de humedad también son los correctos van entre 50%/60% de humedad relativa. Por supuesto el Ph lo estamos dejando alrededor de 6. Hasta aquí es todo, buenos humos 💨💨💨

The growing cycle it self worked out as expected, except that the pH-level was way off from where it should be, and I found out a bit too late. Because of this the outcome of the harvest didn't say much about the potential of this strain, but as soon as I got enough time and space, she will get a new chance to shine. 2018-03-01. This is my review / smoke report of this lovely cbd flower. There are rock hard buds and almost no give at all, even in those smaller buds. When you grind it the scent will appear more than just smelling on the buds. It smells a little weak of grass, wood, bark, sweet, lemon, honey, skunk and some kind of spice. The taste is orange, mandarin, honey, bark, popcorn and pepper. The effect is directly, the thc feeling above the eyes and in the forehead, it fells like its a higher thc levels in this strain compered to the cbd strains i tried before. A little light ringing in the ears and a slight dry mouth. After 10 minutes, the cbd kicks in and and balance the thc high. The neck and shoulders begin to relax and the feeling continues down over the back and chest down to the stomach. A calming, relaxing, and slightly energetic feeling. After 15-20 minutes it is down in the legs and feet, and you can feel a vibrating feeling in your muscles, joints in a pleasant way. It reduces my tense muscles and some of the nervpain i got. Its a good strain for releasing stress and get you in a relaxed and satisfied mood. It is a very well-balanced strain and it fits in all sorts of contexts. If you take this in the morning or mid day it will give you a small energy boost and get you in the mood for doing something. I think this is a lovely strain and I highly recommend it to everyone but especially for more inexperienced people that dont like the high thc strains and want to have a good relaxant, pain controlling, anti depressant medication that also can give energy or help with getting to sleep. This is a must try strain.

Que recomiendas? Saludos gente buena y mucho ánimo a todos! ✌️

-plants are looking alright -Gorilla Zkittlez turned purple (probably because i missed one watering) -now fertilizing again ( i paused it for a little over a week) -think they will need a few more weeks or what do you think? happy for any comment :)

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]

Bedankt @Weedseedsexpress voor de sample 👌🏽 Een prachtige strain. Ze had niet veel aandacht nodig. Haar buds zien er verrukkelijk uit. Dikke compacte buds vol met thc. Ben zeer benieuwd hoe ze zal smaken. Ik heb de plant in zijn geheel opgehangen en dus geen nat gewicht genoteerd. Als het droog is zal ik de buds wegen en natuurlijk proeven. Dit zal ongeveer 2 weken duren. Tot dan 👍🏼

26-05-2025 I forgot to measure my plants last week, but it seems they have gained some leaves and some height! I’m waiting for the weather to be warmer to put them outside. 28-05-2025 I transplanted my plant to the vegetable garden. It grows between nasturtiums, tomatoes and fava beans. Three weeks ago I added green Culterra (N10-P4-K6) to my soil. I hope the soil absorbed it and my plants can benefit from it.

Autumn is here. Weve been setting up the Roof one Day before " Rainingtime" begun. Now every Day we have Rain, Wind and Sunny Times. Up to now everything is OK. They have got a Feeding today Buds are still swelling , Iam hoping for 2 more Weeks of good Weather

31 Aug. I start the third week of my autoflower. The plant is growing well, but I noticed small yellow spots on the leaf tips, which seem like a mild calcium deficiency. This is probably due to the fact that so far I have been giving water with a slightly low pH, around 6, while the ideal range would be 6.5–7. At the beginning, to lower the ppm of the tap water (which was around 211 ppm), I mixed it with demineralized water. This brought the ppm down to about 109–140, making it harder for the plant to absorb the available calcium. Additionally, the soil I am using, Biobizz Light Mix, is lightly fertilized but does not contain enough calcium to correct this small initial deficiency. For this week, I will not add any fertilizers. I simply want to raise the pH to 6.5 and use water with higher ppm, so the plant can better absorb the nutrients already present in the soil. The lamp is positioned about 35–36 cm from the plant and so far there are no burn issues. Temperatures range between 25 and 30 °C depending on the day, while humidity in the room stays between 40–60%. The humidifier is always on because I keep the window open, but the dehumidifier is not being used, as it is not necessary at the moment. I also have a new oscillating fan arriving to replace the current fixed one, and I’m waiting for a regulable extractor (90–145 m³/h), which will allow me to control the air perfectly during winter if needed. This week my main goals are: Increase the water ppm without overdoing it Adjust the pH to 6.5 Keep observing the plant without adding any fertilizers Everything else seems fine and growth is regular. With these corrections, I expect the new leaves to grow healthy and free of spots. ==UPDATE 31/08== To control the calcium deficiency, I will administer an eggshell solution until I reach 300 ppm (I will boil some eggshells and administer the solution in tap water). ==Update 4 Sept== By mistake, I adjusted the pH twice, once to 7 and once to 8, and obviously the plant immediately showed symptoms of incorrect pH. At the next watering, I'll give Biobizz Grow with a little Biobizz Bloom since the plant has entered pre-flowering. I'll adjust everything to a pH of 6-7 and a ppm of 450-500.

Girls are doing great! Tent is very stinky inside. Started watering with 6 gallons now. So 1 gallon per plant with full strength nutes. They seem to want water about every other day. Temps have gone up a little. I had to install a dehumidifier. Also added a large metal 20" fan to counteract the heat from dehumidifier. Averaging around 88 f and 50%RH. About the best I can do without getting an A/C unit. I'm pulling out dead leaves under the bottoms. Still tucking in fan leaves daily to expose buds to maximum light. The buds are getting very sticky and frosty. Had to break out the box of rubber gloves. Or else have sticky fingers with a lingering odor of fantastic. This grow has been fun and looks like a decent possible yield for a noobie. These pics are day 28 and 29 of flowering.

Strap yourselves in this is gonna be quite the revelation update. Day 33 - Northern Lights This girl is fast becoming the pride and joy of the tent showing no signs of flowering yet still well and truly in Veg mode without the female indicators about to end week 5 so she will be getting another round of LST this weekend to maximise freeing up access to light for the parts that otherwise without a Defol wouldn't get chance to blossom. She wants the full tent to herself at this point and the next update is going to help her with that. 20210219_103956.jpg I mean just look at her. She's a monster! Now onto some slightly less satisfying news and an admission of another noob fail. Day 28 - Chemdawg #1 This girl is abnormal. She has already made it perfectly clear she's not far off going into flower so whilst I did tie this girl down for some LST upon inspection from @autobeast he recommended we leave this stocky girl to try and get a bit of height without LST. Now for the admission.... When this girl was topped I cleaned out the top 2 Colas in the process so the top node was literally just two big fuck off Fan Leaves sucking all the good stuff away from the rest so off they came last night leaving this girl with only 6 branches to grow from instead of what should have been 8 had I topped her properly. In a way I'm glad this has happened and I spotted it myself and managed to understand why she wasn't flourishing as much as her cousin. Granted they are different Genetics but you only need to look at the next girls update to see that something just doesn't seem right with this one. 20210217_222845.jpg Here's what she could've won but instead we are going to be leaving her to her own devices. I am a little gutted about this as I've only been able to observe the Defol and training on one plant before I'm let loose with my own little lady that you're about to see next. Here's how Chemdawg #1 is looking today. 20210219_104008.jpg Don't get me wrong she is very healthy and happy and already kicking out that dank stardawg aroma and she may surprise with some fat nugs but I expect her to be having a shorter life span than the Northern Lights and with this in mind I'm going to apply that insight to the 3rd girl. Day 19 - Chemdawg #2 With the mistake in mind from the previous Topping I double checked with AutoBeast on where to top this and I'm kinda happy that he just stayed silent and said top it where you want its your baby. So being careful not to cut the top cola off too I chopped her head off and cheered her up with 1L of Water with 2ml BioBizz Fish. I've also been adding a foliar spray to her of the biobizz FishMix. Once the leaves reach the edge of the pot I'll be starting with 4ml of Parts A and B of Monkey Nutrients Grow Feed and 1 tablespoon of Blackstrap Molasses every 3 days. This is my favourite 6 days of growth I've witnessed so far as the plant tries to decipher which of its Colas is dominant. 20210219_104018.jpg Summary Don't top your main cola off when you realise what you've done it'll hurt like hell. Approaching 2nd week of feed keep a closer eye on the water levels in your plant they get thirsty sometimes but other days not so much so there is no one size fits all in those weeks 4-5 in my experience so far in Organic. Not all plants have the same life span so if growing a variety in one place understand that they will all veg and flower at different ages so while it's nice to have rules of thumb ie no earlier than x to top or no later than day x to start feed there will always be flex between days and that applies even to the same genetics although perhaps not so prominently variant. Every day growing is a day learning. Ok so it's end of week 5 for this @fastbuds_genetics @fastbuds_backup_account @420fastbuds Northern Lights Auto and well just fucking look at her. She's taking over the tent with her canopy dwarfing the 2 Chemdawg Autos and only just showing signs of Preflower. A vast contrast from the 2 Chemdawg but the aerial view gives an idea of the incredible amount of Bud Sites formulating on the upper canopy. I've been leaf tucking twice a day this week for around 15 minutes each time talking to my girls about what I'm doing to free up light to the lower canopy and its bearing fruit for sure. I knew this week was going to be an eventful one for this staggered tent but having thought the Chemdawg had fallen behind she is in fact further ahead in her life so adjusting the feed schedule for the baby accordingly. Every day growing is a day learning.

Sigo abriendo doblando y atando las ramas laterales para abrir las niñas y que ocupen todo el espacio de la malla ,una de ellas va mucho mejor que la otra

Buds a still forming and looking good. I've cut the co2 going forward and will go wihout for the rest of the grow so the buds can rippen. Buds have a lot of frost so far so that's a great sign for the THC. Plants in the tents out of nowhere have spider mites but this plant didn't have much compared to others. Hopefully the last 3 weeks go by fast

.

Beginning of week: Can't tell yet if the branch i broke is going to mend or die yet. Light defoliation today focusing on the upper canopy and tapering to the bottom to allow the lower branches to catch up as much as possible. Midweek: going away for 3 days. Put my net down to help breakup the canopy more though it wasnt really needed this thing loves to grow sideways. Added Cycos suga rush at 1ml/L and a light defoliation. The branch i thought I broke hasnt shown any signs of dying and has continued growing 😁 I also have started watering with worm casting tea in between feeds.

She is doing really great and buds are astonishing! Switching to Overdrive this week
