Heracles (First grow on coco)

Daily report: Day 1. Watering: NO Stats: Humidity: 70% Temp: 27.2 Notes: I want to see how often should I water Heracles. I fucked up with pH and maybe with watering frequency. I want to fix that. Also set the board to 100%. Day 2. Watering: NO Notes: Defoliation went a bit too aggressive, but it looks fine and I hope that it will help weaker stems to grow faster. I will let Heracles to heal tonight and feed her only tomorrow's morning. Day 3. Watering: 5.7 pH 1550 ppm (1.25 l + CalMag) && 5.8 pH 1320 ppm (2.3 l + CalMag) + 5.7 pH 1120 ppm (1.6 l + CalMag) Total 5.15 l => 5.9 pH 1720 ppm (1.25 l) Notes: This morning pot was completely lightweight and dry. Heracles looks amazing. Day 4. Watering: Night - 5.8 pH 1190 ppm 3.5 l (+CalMag) => 6.0 pH 1890 ppm 0.7 l Notes: New leaves still has yellow marks between veins. I don't know what should I do with that - neither MgSO4 foliar nor CalMag in the mixture helped. Currently 1.5 days is the comfy period for feeding schedule. Day 5. Watering: NO Notes: I found signs of overfeeding (and not only me found that), so next mixture will be less concentrated to let Heracles relax. Also, I bounded all tallest stems to the net to place all the grow spots at the same height. Day 6. Watering: Morning - 5.7 pH 761 ppm 4.5 l (0.75% of Base +CalMag + 1 l of plain water) => 6.1 pH 1750 ppm 1.1 l Notes: I am still trying to create a flat screen of greens. Very excited of flowering stage, it's almost here. But wtf is going on with ppm in drainage?! Day 7. Watering: Night - 5.8 pH 1040 ppm 4.0 l (0.75% of Base +CalMag) => 6.0 pH 1930 ppm 0.8 l Notes: I am run out of a free space in my growbox. Why does not blow starts?
