Decided to start dark period(24-48hrs) day 85 mostly milky not much amber maybe some amber on the sugar leaves. I wanted to go 90+days with this auto but I needed the space in the tent for my photos and she looks almost ready, would’ve liked to see a little more amber but nevertheless I haven’t grown much at all so don’t have too much preference yet on trichomes. I’ll chop in a day or two and dry in my smaller tent and hopefully it goes well, my first harvest I dried too fast in low humidity and wasn’t that pleased with the end result. This time I’m planning on lowering exhaust speed and to not be so scared of 50+humidity in drying area and raise it to around 60humidity after a few days. Can’t think of anything else to write, but I’ll update after the chop and dry and 🙏 hopefully all goes well.

March 29, 2024 Day 43 This week will focus on watering and light intensity. Training is done for the most part. At least the structures are on point. Now it's just a matter of keeping the canopy level. So far everything looks great! There's a couple branches on each plant that aren't quite as tall yet, but they are strong. I expect them to grow quickly very soon. The plants are 14" tall now and will definitely be taller by the end. If I'm right, I should get a height of 24" to 36" total. Unless both stunt somehow, but I don't think so. Anyway, just by the health and current growth time and amount, I can expect some robust plants. The buds are going to be super heavy. Just by looking at the bud structure now, tells me I'm going to have to fat dense and sticky weedy do. I changed the lighting as I was scheduled to do today. The light was at 22" from the plants growth. For the week, I reset the light height back to 24" and increased the light power back up to 90%. The DLI is 44 mol/m²/d. PAR should be around 675 ppfd. However, as I said at the beginning of the grow, I focus on DLI over everything else. PAR is fine, I just prefer the DLI. It tells me more I think. As it's a new week, watering needed some maintenance. I cleaned out the other reservoir and filled it up with the new nutrient regimen. That includes the B-52 today and Sensizym next watering for when it gets here. I had to look up a good feeding schedule specifically for autoflowers and advanced nutrients. As the time is all wrong with BudLabs. It's designed for Photoperiods only. So things needed to be adjusted. For example, I'll be starting Big Bud later this week as it calls for week 2 of flower with a photoperiod. But the schedule I found makes more sense and calls for the Big Bud a week earlier. Anyway, it's a good schedule. Just makes sense. The environment will be staying the same this week. 77° and 55%. In the next 2 weeks, I'll drop the temp down to 75° with the humidity at 50%. Then I'll drop it weekly until I get to the final week. I'll drop the temp down to 73° and the humidity down to 40%. 35% if I can manage. However, I'm not all that worried about 40% to 45%. The space is extremely clean and the room itself is really dry. So no worries. So, now that the auxiliary branches are just as tall as the side branches, Banana Purple Punch B has an extremely level canopy. The branches have all caught up to the top and everything is looking great! Banana Purple Punch A is doing the exact same thing. They are both the same height. I wonder if that is the plants keeping up with each other. Like a reaction to the other plants in the tent? Who knows. This is my first completely level canopy for all 4 plants. Very happy so far. As long as none of them take off, we should see a beautiful ocean of fat buds throughout the whole tent. Grow System Environment: Temp: 76.0° RH: 53.8% VPD: 1.38 kPa March 30, 2024 Some notable information today. I'm very curious about this, so if anyone knows what's up, leave me a comment. Thanks! Banana Purple Punch A is taking in way more water than Banana Purple Punch B. I believe now it has to do with the roots. The bottom of the container for Banana Purple Punch A is FILLED with roots, while Banana Purple Punch B doesn't have any roots showing yet except for the bottom outside of the container. I thought the roots would have shown up by now. The thing is though, Banana Purple Punch A is still roughly the same height as the rest of the plants in the tent, but clearly is further along than the rest. Not saying she isn't growing, she is. It's just that she should be stretching like crazy right now and she isn't. The canopy is staying level. I will say that the Tropicana Cookies sharing the tent is slight taller and stretchier. It's ok though, the SCroG net is going up at 18" from the container base. Anyway, it's kind of confusing how these two plants are growing in such a different way, but not any bigger or smaller than the other. Insight please. Lol. Both ladies got a haircut today. Just clearing out the massive leaves that grew and some of the outside leaves to keep them in their own quadrant. It worked wonders. No stress, no issues so far that I can see. I also had to lift the light a couple inches today. The DLI was actually a bit higher than I wanted and it showed last night with one of the plants. A bit droopy before lights out. That tells me there's too much light in that one quadrant. So the light went up to 25" from the canopy. I could drop the power level, but I really like this footprint. Dead center of the tent is around 48 mol/m²/d while the outside is at 43 mol/m²/d. What a spread. Honestly though, I really want a bar style light setup. One for a 4x4 so it fills the whole 3x3 tent. Back to watering. Banana Purple Punch A got a full gallon today. She's drinking a half gallon a day now. I also realized the nutrient schedule I'm using doesn't have the Tasty Terpenes in it. So I started that today as well as the big bud. I also increased the Cal/Mag dose from 4 ml to 8 ml. Big Bud and Tasty Terpenes are both at 4 ml/gal. I also added this week's dose of Recharge. HOWEVER... The PH was Way off. Down to 5.4, so I dosed the shit out of it with PH Up. I got to 6.18 and that's where I stopped. The nutrients are supposed to be PH Perfect, but adding something slammed it down. So I'll start to PH before adding nutrients. Then I hopefully won't have to dump 3 ml of PH Up in a gallon of water. However, I will say the PH in our tap water is ridiculously high at like 8.2, so that may be a factor. But shouldn't the high PH balance out the PH with nutrients? No real clue what happened. It doesn't make sense. It definitely has to be one of the new nutrients. When I do another mix, I'll PH after each nutrient. That way I can see which nutrient is messing up my perfection. I've also read that a PH of 6.5 to 7 is ideal for the flowering stage. Is this correct? If so, how the hell do I get the PH to increase more? Or is my PH meter out of calibration? Damn, things I need to learn. Moving on. The environment is a bit off. The temp is kinda high at 79.5°. However, the humidity is perfect at 55%. Unfortunately the temp is throwing the VPD way off. It's now 1.50 kPa where it should be around 1.33 kPa. I'm trying to fix it, but it takes time. It should be fine by this afternoon. Grow System Environment: Temp: 75.9° RH: 54.5% VPD: 1.35 kPa March 31, 2024 Not much to do today. The plants are doing their thing. Banana Purple Punch A drank about a half gallon from yesterday's reservoir top off. She'll definitely need to be watered tomorrow though. In which case I'll be adding the Sensizym. However, Banana Purple Punch B needs a reservoir refill today. Not first thing, but maybe just after noon. The reservoir is nearly empty, not enough to fill, but enough to be completely dry tomorrow. That can't happen with this system, so I'll have to refill today. I'd also like to note the lack of roots on Banana Purple Punch B. There are none. I'm really confused now. One would think the roots would be through by now. I hope they didn't just stop there. Hopefully I start seeing them in the next couple days. Banana Purple Punch A has roots through everywhere. Honestly, it seems as though growing in my setup with my techniques extends the veg time. That's the only thing I can think of. The lack of roots shows lack of growth. But it's an Indica dominant phenotype. Maybe the root system just takes longer. But she's definitely in flower. Still waiting for the stretch to start, by the way. They are both 14.5" now with yesterday being 14". That's not stretching. I seriously cannot have small and big plants together in this size tent. Maybe if it were a 4x4, it would be fine, but a 3x3 is much smaller... Weirdly enough.... and for 4 plants, there just isn't that type of space. I'll will absolutely implement the SCroG net if things get out of control. I'd rather not use it yet though. I still want to be able to pull them out and clean out the reservoirs and check over each plant thoroughly. At least until I need the net. But really only to keep the tops from falling over. But training has stopped for these ladies. I don't have anymore horizontal space to train them out. But I have plenty of vertical space. Maybe they will only grow to 24" after all. We shall see. Either way, I'm going for quality, so regardless of the size, everything is in order. Maybe they average on the smaller side. Still, they have really packed buds already popping up. They will definitely be super dense. I didn't move the light today. No point. The plants are very happy and reaching slightly. Just a nice little prayer. The environment is really good. Sticking at 55% humidity and the temp has been steady between 76° and 79°. Very nice. The VPD is happy as well. Grow System Environment: Temp: 77.4° RH: 54.6% VPD: 1.43 kPa April 1, 2024 Not much to do today. Banana Purple Punch A got her full gallon top off. I also got the Sensizym in so that went in as well. Also, I need to calibrate my PH meter. It seems to be reading low. Maybe. It's reading 5.4 with PH Perfect Nutrients. I also added a full 1 ml of PH up. It brought it up to 5.49. No idea what's happening. Both plants grew a couple inches last night. Now they are at 16" tall. Let the stretch begin! Banana Purple Punch B is just hanging out. Still not drinking as much as her sister plant, but still very healthy and happy. The roots aren't showing either. Still confused by that. I had to cut a couple leaves off each plant today. Just a bit of overcrowding. Like 2 leaves each. Not much, obviously, but it's still important to notate. And good to keep up with the leaf coverage. I raised the light nearly 2" today. It was too close, and the DLI was close to 50 mol/m²/d with the center being 58 mol/m²/d. Now the DLI is sitting pretty at 45 mol/m²/d with the inside being closer to 50 mol/m²/d. However, I have an advantage. The center of the tent is not filled in totally. I did this on purpose to keep the light intensity fairly even throughout the canopy. (I really need to get a bar style light.) The environment is pretty good today. It's a smidge off. The temp is cooler at 75° with the humidity being closer to 58%. So the VPD is slightly off at 1.20 kPa. It should adjust accordingly in the next few hours as it has been. However, the daily average is right on point. Grow System Environment: Temp: 75.4° RH: 55.2% VPD: 1.31 kPa April 2, 2024 A bit to do today. No watering or anything, but I did some defoliation and raised the light an inch. Banana Purple Punch A got a bit more trimmed off than I had originally intended, but I wasn't off by the mark completely. So it should be all good. She also grew another 2 or so inches and is now a bit taller than her sister plant at 19". Not much, but enough for me to notice. She looks great! Roots galore, beautiful green color. Fat buds and a wonderful aroma. She is 19" and still stretching. Let's see what she turns out to be. Banana Purple Punch B also got a haircut. She definitely needed it. In 2 days, she completely filled back out and needed to be opened up a bit. As I said before, I have stopped training, so if she doesn't catch up, which she may, I'll have to lift her up to the canopy. She's 18" now. An inch or so shorter than Banana Purple Punch A. However, she finally has roots showing throughout the bottom of the container. Nothing crazy, but lots of them popping up. It should be a matter of a couple days and those roots should be pretty long and sucking in water like crazy. Maybe not as much as her sister plant, but much more than she is now. Also, I think she may end up being a much more robust plant than her Banana Purple Punch A. The roots took longer to hit bottom and that may mean the root ball is already massive. That being said, I can hopefully expect her to take off and catch up to the rest of the occupants in the tent. Like she's setting up to stretch. The light definitely needed to be raised again. It was all the way down to 22". I may raise it again if I don't see praying. Anyway, I dropped the DLI back down to roughly 45 mol/m²/d. It should be good now. But may be a tiny bit too high. I'll see what happens in the next couple hours. The environment is pretty good today with the temp hovering around 76° and the humidity at 55%. The average for the day looks great as well. Grow System Environment: Temp: 74.2° RH: 58.2% VPD: 1.18 kPa April 3, 2024 Today has been enlightening. The plants weren't reaching this morning. That meant the light was too close. So I lifted it up AGAIN. I'm running out of space between the light and the exhaust fan. I still have a good 6" or so left. I can also lower the power level if need be. Both ladies got reservoir refills today. Banana Purple Punch A was still a out half full, but Banana Purple Punch B was empty. So now that they are the same level and seem to be drinking roughly the same amount now, they should drink evenly now. Banana Purple Punch A is about 21" with Banana Purple Punch B slightly behind at 20". Either way, they are growing quite nicely. The stretch is in full swing now. I may have to put the SCroG up afterall. Some of the tops in the canopy are starting to take off. I'll install it tomorrow when my side bar support gets here. The lighting, as I said, needed to be raised up again. The DLI was up to 50 mol/m²/d and now I have it back down to 45 mol/m²/d. I also have the light distance just above to 24". Should be good for now. The environment is a bit off today. It's raining and the humidity is a bit high even with the dehumidifier on. The humidity is stuck around 59% with the temp staying around 75°. Hopefully it adjusts in the next couple hours. I may have to turn my main dehumidifier on. It doesn't work the best, but it should be fine. Grow System Environment: Temp: 75.6° RH: 56.2% VPD: 1.29 kPa April 4, 2024 Not a lot going on today. I got my side bars in and mounted the SCroG net. Some of the tops are noticably taller than the others, so they needed to be taken care of. No watering today. The reservoirs still have water in them. They might not need water tomorrow. I'll see how things go. I didn't move the light today as I am pushing the tops down some. I may have to turn the power down a bit if they stretch as tall as I hope, but that would be a good thing. I'll just make sure to use the supplemental lighting I have for the tent. The environment is actually pretty good today. The temp is 76° and the humidity is at 55%. The VPD is basically perfect at 1.33 kPa. So everything looks pretty good from here. I'll start dropping the humidity down more in a week or so. Just after the stretch. Grow System Environment: Temp: 75.5° RH: 54.8% VPD: 1.33 kPa

So I have decided to only note when changes are made, observations are warranted, or I feel something of note has happened. I'll still do daily progressions, but the rest has already been documented and no need to create a hundred new pics showing the same. Just understand that if I say "7.1ph," or something with tested amounts that I mean I first calibrated and tested my ph pens and all units are measured for accuracy. I am learning as I go, so it would be of no benefit to report inaccurate details. 112/42 VPD and PPFD are still the same this week. 73-76F in the day and 66-68 overnight with RH set to not exceed 55% but is mostly at 45 to 50% now that winter is here. The fan is set to auto and I have 2 de-humidifiers in the tent. The PH lockout issue is still in progress but I am starting to get the soil up to snuff now. I think using the knitting needles has the most beneficial effect on the soil as it both aerates and allows the nutes to get deeper. 113/43 Defoliated today. I removed the worst of the affected fan leaves and this unfortunately only leaves sugar leaves to run photosynthesis process. Im hoping she still gets enough of everything else to grow the buds, but only time will tell. I will take new control pics for new progression on 3 other sites now. Watering Days. All feeds with nutes use either a whole ratio, or combination, of "Veg Mix" and "Bloom Mix"concentrates. These are/will be DILUTED in water until a total ppm of add-in is reached using a (Total Dissolved Solids) TDS Meter measured in PPM (parts per million). The "Veg Mix" concentrate will eventually be added-in larger, then smaller, ratios while the "Bloom Mix" concentrate will eventually replace the "Veg Mix" concentrate entirely. The ppm and ratios will be listed when I feed. Veg mix recipe is on week 3. Bloom Mix recipe is on week 5. Last feed was day 110/40 (next will be +3) I expect to continue to use 7.1ph with 650ppm of bloom mix concentrate and feed 2.5 gallons every 3 to 4 days, so I expect about 8 to 11 cups of runoff at that time as well. I have decided that I will try to add 1 ml of CaliMagic (General Hydroponics 1-0-0) per gallon of feed on each feed for a week or two to see if this can help against ph lockout of calcium since it cant be N,P, or K. Cant be N because she uses WAY less N in flower, and it cant be P or K because I am getting nute burn with the feeds I am already using... so my conclusion is that she need more micro nutes from the lockout, and since I was thinking it was Calcium in the start, I am going to try a more detailed treatment to test results against from here. Day 113/43 (last feed was day 110/40) Tested and Calibrated my ph pens. Fed 2.5 gallons of purified water (starting with 16ppm) mixed with 658ppm of 100% Bloom Mix Concentrate. Due to this soil showing a possible calcium deficit, I am starting a 1ml per gallon add-in to test on all plants using this soil, so I added 2.5ml of CaliMagic (General Hydroponics 1-0-0) to the feed then I ph balanced before feeding. The ph on this feed was balanced to 7.1. I used knitting needles to help both aerate the soil and create new water pathways for the roots. (a practice I may consider a new feeding standard for all my plants) I got ~7 cups of runoff (~11 cups last feed). Higher runoff volume was expected with the feed volume but glad to see she's taking it better now since I started knitting needles. Runoff was tested at 6.12ph and 2250ppm (5.9ph with 1860ppm last feed). Top soil tested at 6.23,6.31,6.57,6.38 for an avg of 6.372 (6.327 avg after last feed) - next feed will be 7.1ph again as I'm still liking where the ph is finally going, but rather see it closer to 6.3 or 6.4 top and bottom. I dont see any issues with the feed's data other than the possible calcium deficit and I will continue to monitor runoff ppms as I expected this to be lower with less runoff but have to consider they maybe washing out salt with the knitting needles. Next Feed should be 3 gallons of de-chlorinated tap water ph balanced to 7.1 in +4 days (117/47). I will run 650ppm and 3ml of CaliMagic (General Hydroponics 1-0-0) again. Day 117/47 (last feed was day 113/43) Tested and Calibrated my ph pens. Fed 3 gallons of de-chlorinated tap water (starting with 299ppm) mixed with 671ppm of 100% Bloom Mix Concentrate. Due to this soil showing a possible calcium deficit, I am starting a 1ml per gallon add-in to test on all plants using this soil, so I added 3.0ml of CaliMagic (General Hydroponics 1-0-0) to the feed then I ph balanced before feeding. The ph on this feed was balanced to 7.4. I used knitting needles to help both aerate the soil and create new water pathways for the roots. (a practice I may consider a new feeding standard for all my plants) I got ~20 cups of runoff (~7 cups last feed). Higher runoff volume was expected with the feed volume increase might let her go to 4 days again and 2.5 next feed. It could be a result of the knitting needle treatment when feeding. Runoff was tested at 6.10ph and 2070ppm - again thinking it could be a result of the knitting needles (6.12ph and 2250ppm last feed). Top soil tested at 6.23,6.31,6.57,6.38 for an avg of 6.372 (6.372 avg after last feed)- next feed will be 7.1ph again as I'm still liking where the ph is finally going, but rather see it closer to 6.3 or 6.4 top and bottom. I dont see any issues with the feed's data other than the possible calcium deficit and I will continue to monitor runoff ppms as I expected this to be lower with less runoff but have to consider they maybe washing out salt with the knitting needles. Next Feed should be 2.5 gallons of de-chlorinated tap water ph balanced to 7.1 in +4 days (121/51). I will run 700ppm and 2.5ml of CaliMagic (General Hydroponics 1-0-0) again.

Hey guys :-) . This week I will use LST again, and everything radically shorten 🙈. Not because I want to, but because I still have to save some time and height because there is still no space in the bloom chamber for 35 days 😂. It grows great so far, and as with the last grows it is beautiful with it 😍👍. I wish everyone a nice week 🍀🌱.

First week of flower these girls are definitely ready to start producing. I have lollipopped them and have done a tone of L.S.T. with little super cropping to start building that strentght for big colas. Extremely excited about this run. These mac and jac girls were under a marshydro fc 4800 all of veg and switched to the spider farmer sf 4000 to finish the run. Lighting has switched from a 18/6 to a 12/12. Earthy smells have become stronger. The plants are very healthy and growing strong best of luck to your grows to all my growmies hope you all a plentiful harvest.

Very easy strain to grow. I grew the White Critical Express previous to this grow, I really liked it and wanted to try growing an Autoflower so I went for the Critical 2.0 and it was worth the grow.

Well it seems i ran into some sort of issue and had to flush. I hope it fattens a bit more even though i feel like the issues may have something to do with the root system. I am at day 44 out f a 55-65 day flowering plant. I just hope i can get through this so that i can start flush this friday and harvest in like 2 weeks.

Nothing but water this week. They have slowed down drinking. Think there just about done. Probably chop in the next few days it looks like having two in the earth box is really going to effect yeild. If I was to to this again I would flip when they are much smaller

I believe the plants still have a little stretch in them. They have not grown much since the bud production picked up last week. The berry bomb still seems to work well off lite nutrients. The smell has started to choose days that it stinks, and days it is invisible. I live in a legal state; I am allowed up to 12 plants. Smell is not a issue for me. I do not need to hide my grows. I had to set up a wire tie on the plant in the videos. She started to lean right. While setting it up the smell that stuck to my gloves was very fruity. I cannot wait to smoke the final out come. The berry bomb auto has been super resilient to most common grow issues. She also bounces back insanely quick fro stress. This is not something I have seen in many auto flowers due to the limited time they have to grow, and bud. I am so impressed by the genetics of this plant. I'm just blown away with this grow.

This is a fastflowering test strain and I have no real information on the genetics. I'm guessing the flowering time of 58 days is about right for a fast flowering strain. I trimmed her after 12 days of drying and got 32g of decent solid buds and 10g of not as dense buds that may go with the trim to make some hash. Stats for the grow. FFNA2410=42g FFNA2411=45g FFNA2412=43g Acapulco Gold=44g Total=174g Expected hash from trim 28g Power used for whole grow in 114 days. Lights=201.7Kw (201.7×0.25)(=£50.42) 201.7÷114=1.769kw per day light average. Average 100w for veg Average 150w for flower. Light average for grow 125w. 174÷125=1.39g/W for the light.
