P2 & P3 - ILGM Blue Dream 4x4 tent grow

Wednesday, Oct 11 (Day 43) - I think this will be my final week of vegetative growth. Continuing to train via supercropping and LST. Jack's Nutrients has a Bloom 10-30-20 to use with Epsom salt for the first week of flower. This, then, may be my final batch of veg nutrient solution. (Although, most of flower is the same stuff according to Jack's Nutrients schedule.) I made another 24-gallon batch in my nested 32-gallon tote: 1. 24 gallons tap water (EC 0.420) 2. 60 mL Armor Si (then wait at least an hour) 3. 121 grams Jack's Nutrients 15-5-20 and 24 grams Epsom salt (I ended up needing about double this to get the target EC...) 4. 120 mL General Hydroponics Diamond Nectar (Used up my supply of RAW humic acid.) 5. 3/4 teaspoon Yucca ..... Check and adjust EC to goal of 2.1 + tap = 2.520. Actual result: _2.636_ ..... Adjust pH to 5.8-6.2. Actual result: _6.0_ 6. 30 mL RapidStart (I'm almost out of this stuff; should I get more? It's pretty expensive...) 7. 60 mL H2O2 Grow light power has been 100% the last couple of days; today, I made sure it was 16 inches from the canopy. My original plan was to grow four Blue Dream plants and I think a 4x4 tent would clearly support that. ----- Thursday, Oct 12 (Day 44) - trying to keep an even canopy with mostly LST. ----- Friday, Oct 13 (Day 45) - they look good to me. I'm unsure about trimming at this point: What's the goal for just before switching to 12/12? I've read to veg until your height is 1/2 to 1/3 the final height supported by the setup. ----- Saturday, Oct 14 (Day 46) - I'm going to make the above question a grow question to get some advice... ----- Sunday, Oct 15 (Day 47) - Thanks to all who answered my grow question! ----- Monday, Oct 16 (Day 48) - I'm still just kind of letting the last bit of vegetative growth happen. I'm pretty happy with how they're looking! ----- Tuesday, Oct 17 (Day 49) - Not much volume of run-off anymore, likely because of how much the plants have grown. I increased the duration of each fertigation from 25 to 30 seconds (20% more.) I have a trellis and was thinking of using it, maybe for ScrOG or at least just for extra bud support. After reading again information about ScrOG, seems that may have made more sense earlier on, along with less manifold/mainline-based topping. I read NebulaHaze's defolation tutorial from her website (growweedeasy.com) and will be utilizing that guidance: Immediately before switch to 12/12, I will completely strip the leaves (leaving bud sites) from the lower part of each plant that is currently in shade, as well as removing bigger (but not all) fan leaves from the canopy, to the point that stems are easily seen, making sure not to damage bud sites. She recommends a second defoliation two weeks later, then mainly tucking big fan leaves to keep bud sites exposed. So, I'm planning on doing that tomorrow morning. I'll also use the remaining veg nutrient solution as a kind of salt flush, hand-fertigating the two plants whatever is left in the 5-gallon reservoir and the big tub reservoir. I'll clean the reservoirs and pumps, etc. and make up the Bud Set fertigation solution for this first week of flowering. I'll defoliate as described and change the light schedule to 12/12 (likely 1930-0730.) I'm excited! ----- END OF 7TH WEEK FROM SEED
