P2 & P3 - ILGM Blue Dream 4x4 tent grow

Wednesday, Sept 20 (Day 22) - Calculations for 20 gallons of veg nutrient solution (I was going to do 28 gallons but my container looked too weak, the sides bowing out, so this time I just did 20 gallons): In 20 gallons of tap water... 1, Add 50 mL Armor Si (silica) and wait 1+ hours. 2. Add Jack's Nutrients 15-5-20, 100.94 grams, and Epsom salt, 19.79 grams. (Nutrient schedule says 504.72 grams 15-5-20 and 98.94 grams Epsom salt pr 100 gallons.) 3. Add 5 tsp RAW humic acid 4. Add 5/8 tsp RAW Yucca (wetting agent) ... measure EC and adjust if needed. Tap water was _0.462_ and goal for total is 2.1 + tap, or __2.562__. Ended up with _2.416_. ... measure pH and adjust to goal of 5.8-6.2. Ended up with __6.0__. 5. Add 25 mL RapidStart. 6. Add 50 mL H2O2. ----- Thursday, Sept 21 (Day 23) - (Focused on Plant 1 which I eventually decided to abandon.) ----- Friday, Sept 22 (Day 24) - Late at night I transplanted plants 2 and 3 into 5-gallon pots. ----- Saturday, Sept 23 (Day 25) - I hand-watered each pot to ensure saturation then arranged it so each has two drip emitters. I changed the duration of each timed fertigation from 20 to 30 sec then 40 seconds. I estimate each fertigation should be ~3 cups nutrient solution which at 6x/day would be 18 cups or 1 1/8 gallons. For a few different reasons (see first diary for this grow for more explanation), I decreased the EC. The nutrient schedule for Jack's Nutrients suggested no need to work your way up slowly but it clearly would've been safer for me to do that. Their feeding chart shows that for vegetative growth, the EC should be 2.1 plus the tap water (for 15-5-20.) Tonight, I reduced by 5-gallon reservoir nutrient solution EC from 2.566 to 2.048, ~20% lower. I pH'd to 5.9. *[Note: Plants 2 and 3 had five days of nutrient solution (Days 14-18) that had 10x the magnesium.] I topped plant 3 tonight. ----- Sunday, Sept 24 (Day 26) - (I gave up on Plant 1 and pitched it. That had been the impetus for the first diary. After today, content will be new. Up until now it's been mostly summarized from that first diary, edited to focus on just Plants 2 and 3.) At this point with Plant 1 gone it's just Plants 2 and 3. I adjusted the Mars Hydro drip emitters so each plant has 4 emitters. Each fertigation is set for 20 seconds which should be about 2/3 cup per emitter or 2 2/3 cup per plant per fertigation. At 6x/day, that's about 1 gallon per plant. When the plants are flowering, I'll likely increase the fertigation duration to 30 sec which would be 4 cups per fertigation total, and, at 6x/day, 1.5 gallons per plant. 4 cups is 5% of the volume of a 5-gallon pot. I topped Plant 2 and trimmed all leaves below that 3rd node. I've decided Plant 2 will be Manifolded as credited to Nebula Haze, which from my reading is topping twice, accomplishing eight branches by topping and training after the first topping so each side after the first topping ends up with four branches. I've decided Plant 3 will be Mainlined as credited to Nugbuckets, which from my reading is topping three times at symmetrical nodes to produce eight equal main branches. (I know some of these terms are interchangeable/overlap, but this is how I'm thinking about them.) ----- Monday, Sept 25 (Day 27) - Plant 2 is recovering from the topping/trimming that it went through yesterday. Plant 3 seems to be doing well. I supercropped and tied down the branches growing from that first topping to help them grow out from the center more. (My first time that I am sure I did it correctly. I felt the pop in the branch when I squeezed it and the result looks just like lots of pictures in tutorials I've ready. Yay!) EC of the 5-gallon reservoir today was ~2.05; I pH'd to 5.8. I checked the run-off from yesterday's fertigation and the results were lower than the reservoir EC. ----- Tuesday, Sept 26 (Day 28) - supercropped Plant 2but didn't tie down. I'm continuing to try to train Plant 3. Refilled 5-gallon nutrient reservoir: pH'd to 6.0 and EC ~2.0. Run-off was low at first, I thought, but I think I forgot to switch mode to EC from PPM. When I was more careful, the run-off seemed ~0.4-0.5 higher. I'll increase duration of fertigation from 20 to 25 seconds. Eventually, it'll go to 30 seconds and that may be needed now but I'm also trying not to waste nutrient solution. ----- END OF 4TH WEEK FROM SEED
