Die Woche ist ansich gut verlaufen, 2 Pflanzen haben irgendetwas aber ich weiß nicht woran es liegt. Morgen/heute werden alle plants ausgedünnt, und ich werde die beiden Kastenventilatoren rechts und links an den Zelt Wänden gegen oszilierende monky Fans an den Mittel Stangen anbringen, ich spare Platz in der Mittel Reihe den ich brauche. Ich bin sehr zufrieden bisher mal sehen ob ich raus finde was die 2 Pflanzen haben...ansonsten wünsche ich euch eine schöne woche und stay high 😬😁👌 Ach so an Dünge tagen gieße ich immer easy 2L pro Topf. Und dazu von Madame Grow alle 4 bis 7 Tage Flower Karma rauf sprühen das Zeug ist top!👌 The week itself went well, 2 plants have something but I don't know what the reason is. Tomorrow all the plants will be thinned out, and I will put the two box fans on the right and left of the tent walls against oscillating monky fans on the middle poles, I save space in the middle row that I need. I'm very satisfied so far, let's see if I can find out what the 2 plants have... otherwise I wish you a nice week and stay high 😬😁👌 Oh, on fertilizer days I always pour easy 2L per pot. And spray Madame Grow with Flower Karma every 4 to 7 days, the stuff is great!👌😬

So I'm on holiday at the mo. My friend is house sitting (plant sitting) and has sent me a few photos to keep me happy. Not the best quality as over exposed, so I'll upload some better ones when I'm home on Sunday. Worth noting that the light yellowing of the leaves is a result of the over exposure and not a dying plant lol. Looks like good progress. No close ups to see if it's flowering unfortunately, but it's definitely still growing in stature. A follower noticed some leaves clawing at the top of the plant, but it hasn't got any worse in the last week and I haven't actually given it any additional nutes, so fingers crossed I don't have nitrogen toxicity. Gave some Biosyss last week, hoping that it has provided an optimum environment I didn't use LST and wondering whether that's going to mean a lesser yield. Update: asked a question and found that not too late to LST so going to start that Monday when back from hols. Updated with better pictures 👌🏻 Any thoughts? I'm back from holiday tomorrow and planning on starting a feeding schedule of biogrow, bio bloom and topmax to maximise yield 👌🏻 10/10/21 - Back from holidays and have uploaded new pictures. Lots of pistels appearing now suggesting it is going into flowering. I have decided to go ahead and LST despite the stress it might cause. I figured with it being a hardy strain that it may tolerate it, and the benefits (if it works) would make it worth the risk. 11/10/21 - Plants have coped really well with the nutrients. Checked pH today and sitting at around 6 which is ideal. Humidity fluctuates a little. Between 45% and 65%. If keeps going high then I'll put a dehumidifier in. Buds starting to form/flower now. Exciting times

All plants are in good health and after the initial stretching during the first weeks of flowering stage they finally stop growing in high. I began to feed the girls once a week with molasses but it's too early to evaluate results. What I can say about molasses is that it's very sticky, super dense and quite tricky to mix with water. Plant #5 looks drinking less water the the other sisters, in fact the soil is less dry the the other and the pot is heavier. Apart from that plant is growing happily.

5/4 I stupidly watered everything this morning. They were pretty much perfect weight for transplant......then I watered them. Oh well. If that's the worst mistake I make I'll be ecstatic. Went back over and found my 1 gal and 2 of those wierd slanty airports that tapers and holds like a gallon and a half and washed them. I mixed up 12 gallons of soil in a garbage bag and mixed it thoroughly with my gloved hands. It's mixed good. Looking at my plants in sadness thinking, "today could've been the day" and noticed a Special Kush of average size I didn't water that weighed in the 220's. I was happy. I filled the pit arpund a cup before removing it leaving the perfect hole. Mykos and water were poured in. Plant came out of the cup REALLY easy. Suprisingly easy. This wasn't totally dry. I was amazed it came out so easy so I kinda rolled it around looking at the roots. I started lowering it in the hole and I felt something break away but it webt DIRECTLY into the hole made for it. I tucked some soil around it but it was pretty tight from packing it around the empty cup. Didn't take a picture but the plant is fine. That was an average size plant too. So I may have to give some of the strains I popped later a little longer before I transplant. After everything's been transplanted I'll need to change lighting again. I think I'll open the window and use the hps and the l.e.d on the days and nights cThat's these girls won't be hardening off. I so wanna go plant those others but my intuition tells me to wait until morning and it's been serving me well. A couple can stay in cups longer. Not much longer but still. 5/5 Transplanted everything but two this morning into 1 gals with 1/2 happy frog half ocean forest. Mykos and water used during transplant. Found put the l.e.d was on for 24hrs for a while. I made sure the timer switch was ON but it was a different cord plugged in. Oh well. All transplants went perfect. I'm picking up an adapter for the outlet so I can plug the power strip into the timer and only use one timer. I had to hang the 150watt hps back up with the 1,000 watt equivelant 105 true watts. I hope this lighting setup works. Chemdog #4 and One MK Ultra will be transplanted later today or later in the morning. I also opened the shade to the south facing window. Shits getting real. EDÌT: I FINISHED TRANSPLANTING THE LAST TWO PLANTS AND PICKED UP THE ADAPTER SO I COULD HANG THE HPS NEXT TO THE L.E.D. THEY WERE FIBE WHILE I WAS GONE. EASIEST TRANSPLANTS EVER. THEY ALL LOOKED PERKY AND HAPPY SIX OR SEVEN HOURS POST TRANSPLANT. I OPENED THE CURTAIN TO (SOUTH FACING WINDOW) BUT I MADE SURE THE PLANTS WEREN'T IN THE DIRECT LIGHT. EVEN THOUGH IT WOULD PROBABLY BE FINE. LAST TIME I HAD SEEDLING IN DIRECT LIGHT. I'LL PLAY IT BY EAR BUT IM HAPPY. EDIT 2. Went back over to meditate by the stream and do my qigong. It's 75 and BEAUTIFUL today. The girls will be going out for a few hours on days like this. Anyway when I went in I was surprised to see everything looking nice and happy with praying leaves. Nothing is in direct sunlight but damn that window let's in a lot of light. 5/6 Girls LOVED the transplant! They seem to be all happy. No stress. Easiest transplant I've done. Leaves are praying upwards so I think the lights are approx tje right distance. They'll be going outside soon to harden off. It's been in the 70s but it's rainy now. I'll play it by ear according to weather. I'll continue to monitor lighting and I may lower the hps. 5/7 The soil was super dry when I went over this morning. Everything looked awesome though. I used about a half gallon watering. I don't want to water to run off. I want to keep the nutes IN the soil. It's also easier to fix an undet watered plant than an over watered one. It came out to about a half gaterade bottle on the biggest and half that on the smallest. I'll gradually increase water after I monitor the response. The water sat on the soil for quit a while so they definitely needed it. Looking good so far. 5/8 Soil lookeddry this morning. I think I'm going to up the water. Last time I dod seeds I gave like a pink. Some plants still had a little dampness where I watered that I could see. Others looked dry but happy. I gave the REAL dry bigger ones a small circle around the rootball. Just in case. I'm thinking of lowering the hps slightly so it's at least level with tje L.E.D. That window being open gives tons of light. If u moved them slightly left they'd get DIRECT sun most of the time. I'll be bringing them outside soon to start hardening them off. EDIT: WENT TO CHECK THE GIRLS AT 5 TO MAKE SURE THEY WERENT DRIED OUT. THESE GIRLS ARENT JUST GETTING BIGGER BY THE DAY THEYRE LOOKING BIGGER FROM MORNING TO NIGHT! ITS BEEN RAINING LIKE CRAZY BUT WE WILL HAVE GREAT WEATHER NEXT WEEK AND I'LL BE BRINGING THEM OUTSIDE. I'M SUPER HAPPY WITH GROWTH SO FAR. ILL PROBABLY HST (TOP/FIM) AT THE NEXT NODE. I WANT THEM TO SETTLE IN NICELY BEFORE STRESSING THEM. 5/9 I may have stupidly uploaded doubles of pictures from today. Soil LOOKED real dry. I gave the plants their first real watering. I still went light. Almost a gallon with all plants. I know many say I should be watering to runoff but I want to keep the nutes in the soul as long as I can I don't want to overwater. I always start out careful. Once they show they xan tolerate it I'll increase water next time. This weekend it will be raining but after that we are getting some real good weather and I'll he taking the girls out to begin hardening off. I also need to take a look and top/FIM the plants now that they are settled. Also need to wash grow bags and sanitize outside. 5/10 It's pouring out. Horrible night and morning but this is about cannabis. After the watering ALL the plants shot up in size! Substantially. Leaves are over the sides of containers. I think I'm somewhere close with the watering schedule. I may bring the hps light down a little. I also NEED to start HST. I need to FIM and/or top these girls. Unfortunately I've been dealing with medical problems of my wife so I haven't got to it. If I get some sleep I may do something this morning or in the afternoon.

This was my first grow and I did a bunch of research but I mostly figured it out as I went and I really enjoyed this strain. It was very resistant and took about 90-92 days from germination to harvest. The strain seemed to bounce back extremely well even after a heavy trimming. Did not really run into any health issues with the strain other than what I diagnosed as Leaf Septoria which is caused from to much humidity and not enough circulation. But overall will grow again and was very accurately advertised by Canuk Seeds. Ended up with 256grams from this grow which I was pleasantly surprised with. Saved all the shake and made Cannabutter and Bubble Hash. Both turned out okay but with room for improvement in the future.

6/23 Due To The Two 8 Day weeks this week will only consist of five days to get me back on track. SEE LAST WEEK FOR DETAILS. I DID ANOTHER EIGHT DAY WEEK. I'LL DO THIS WEEK AS SIX DAYS. THAT WAY IM BACK ON SCHEDULE. WATERED 6/22. WENT BACK AT NIGHTCAND WATERED ANOTHER GALLON WITH 1/3 TSP Armor Si. I mixed the solution with kelp you kelp me but I dumped it out. I've mixed silica with other nutes before but I had read something earlier about bioavailability issues and I didn't want to risk it. My plants are the healthiest I've ever grown. I'm considering transplanting the large 10th planet that I'm light depping. I also need to develop my ipm and my nute schedule. Still gonna have to keep an eye onvthe water situation. Luckily I have a buddy in my corner that's co tinualkt Bern a great help. WENT BACK OVER AROUND NOON. BEAUTIFUL OUTSIDE AND THE PLANTS WERE LOVING THIS SUN. I DEFOLIATED SOME BURNED LEAVES AND MIXED A SOLUTION IF KELP ME KELP YOU THAT I PLAN TO FEED TO THE GARDEN TODAY. IM HAPPY WITH HOW THINGS ARE GOING. WE HAVE SOME RAIN AND THINDERSTORMS COMING. I NEED TO GET MY IPM UP AND RUNNING AND THE NUTES ONLINE. I ALSO NEED TO DECIDE IF IM GOING TO TRANSPLANT THE LIGHT DEP 10th PLANET. Went back over to put the girls to bed at six and if was still 90 degrees. The water from yesterday had dissipated. The tops were dust dry. I mixed two gallons of kelp you kelp me and fed it to the garden. Afterwards I pointed qbd found a couple plants that were more open to the wind were a little lighter. I know tomorrow will be very hot. Maybe quarter inch of rain. However after that it will rain (showers) off and on for days. I wanted to make sure the girls had what the needed to make it through tjis heat wave until they get that rain. I had another gallon mixed up and I'm thinking I should've given it to them. Oh well. I'd rather underwater than overwater any day. I did notice a burnt top on the plant furthest from the tarp that the sun JUST BARELY TOUCHES when the rest are in shade. I'll just raise the tarp a little. These are tiny problems. Can't upload video until tomorrow. 6/24 Good thing u gave the plants that water. I know it wasn't much but we didn't get any rain. Suppised to get a qtr in today and another qtr in tomorrow. Then rain a couple more days. It's working our really good for my watering schedule lol. Yesterday the girls got there first dose of a bottled nute. They got two gallons of kelp me kelp you (1/3 tsp per gallon) and another gallon of just phed water. I was going to do another gallon but held off due to the threat of syring rain. Didn't get it bur it looks like the plants loved the kelp. It had reached 90 yesterday. They look better today. It's 70 at 9 today. I LST the 10th planet in the 3 gallon. It's getting huge. I should start a separate diary for those three light dep plants. Its cool as hell watching this. One of the purple punches is flowering pretty good. I probably should start another diary for them. I'll be starting to feed my plants soon. Wondering if I should pinch plants again. TUCKED THE LITTLE GIRLS IN AT SIX AND SHOT A VIDEO AND TOOK SOME PUCTURES. PLANTS LOOKED PHENOMINAL! GOT HOME AND AROUND SEVEN IT JUST STARTED RORREBTIAL DOWNPOURS! THE TYPE OF RAIN THAT BREAKS STEMS. I SHOULDVE PUT MY OTHET TARP UP BUT I DIDNT. I WISH I HAD. IM A LITTLE NERVOUS. I KNOW THESE GIRLS ARE STRONG THOUGH! TOMORROW. ILL ROLL THE RARP UP AND SECURE THE BOTTOM FOR FAST ACCESS. IM ALSO GOING TO KOOK INTO FINDING A TOP FOR MY CAGE I CAN USE IN INCLIMENT WEATHER. 6/25 That little qtr in of rain we were supposed to get turned into torrential downpours and high winds. Luckily no REAL damage. If you watch the video you'll see what I mean. I'm going to havecto be cognizant moving forward. Noticed a few chunks from leaves butvplants are still healthy. I'm surprised how well these girls withstood this storm. They are certainly resilient. The 2 purple punch 1 10th planet that I'm light depping are flowering nicely now. They missed all the commotion from the storm as they were inside. It's smelling good. I'm happy. 6/26 It's what a friend would say is "maineing") out. That mistcthe plants love. I'm surprised the plants are doing as good as they have been considering the wind. Will be adding nutes soon. Need to add extra supports too. Light dep 6/27 Brief periods or torrential downpours. Light depped 3 gallon 0lants are under an overhanfcwhete the hatsxrain can't hurt them but they still get sun. They are really starting to flower now! I'm going to begin feeding with a base nute and a flower nute I think. I'm thinking about giving the light dep some open sesame or something similar. I need to set up a nute program soon but the plants ALL look so healthy! And it's been raining! I've only watered like once or twice since they've been in the big pots. I've seen zero pests aside from a chunk missing from a grasshopper. Usually by now I'd have battled half a dozen things and be battling another half dozen. However I was posing from clones. These are seeds and boy don't I see the difference!

A nice stocky little plant. She is starting to get that nice smell. Taking heavy feeding nicely and also now fattening up. Still no purple colours yet. I love this strain.

Final weeks of flowering, she didn't turn purple unfortunately. Nevertheless buds are big and smelly. Leaves are starting to turn yellow, I have been removing old leaves every day. Harvest will come soon. No fertilization this week, only water.

Week 8 Update – Height Issues and Frosty Buds 🌿❄️ No major complaints this week—everything is under control, except for the height of AN#3… but Supercropping to the rescue! 😅 BioBizz#1 – BT30 She’s now using less water, managing 3L every 3 days. Bud development is steady, but compared to AN#4, she’s noticeably less frosty. AN#4 – BT30 This is officially my best and strongest plant so far—super frosty, even on the large fan leaves! 😍 She’s also down to 3.5L every 3 days and thriving. AN#3 – BT26 Not performing as well as the others, mainly due to the light distance. At times, there’s only 4cm clearance from the lamp! She’s definitely not loving it, but I’ve managed to keep things under control with Supercropping. I have to admit, the stretch on this strain caught me off guard, and I’m not entirely happy about it. 😅

The girls recovered the same day as the topping last week. They have more than doubled in height and gain nodes quickly. Accidentally was giving wrong dose of nutes last week and corrected it this week. These strains are very hardy so far

Day 72: 600W LED, 18 hours on 6 hours off the same with ventilation. Ferilization is the same except Critical Orange Punch and Sour Stomper they are being flushed. Water intake also remains the same 200ml per day. Humidity approx 35 percent. Day 74: All good, Sour Stomper needs to.be harvested next week and then Lemon Zkittle and Critical Orange Punch.
