FSTS x Solfire FX3 Grow Off

9/13 Day 8. The one on the right has been falling over a lot the past few days. I redid the wires to keep it upright a few times now, but it keeps finding ways of falling. Pretty sure I have it rigged up 100% now. While both are on track, I did finally discover why my runoff EC was always high and it’s because of the gypsum I have been adding to the coco. After adding perlite, vermiculite, and the gypsum to the coco back when I prepped the pots, runoff EC was 2.4. I rinsed it down to 1.2 for germination, but last night I watered until runoff and it had climbed back up to 1.7. Since I can’t take the gypsum out and this is a grow competition where I can’t just restart the grow, it seems I have no choice but to battle high EC for the duration. I’ll keep watering until runoff for as long as I can before switching to autopots to try to combat the constantly rising EC. 9/18 Day 13. I gave each a flush using plain tap water, and the initial runoff EC was fortunately only 1.5. I flushed until I got 1.3 EC runoff for each, and then mixed up two gallons of my veg nutrients. Each then got 1 gallon of veg nutrients at 1.2 EC and 6.1 pH. Hopefully everything is fine now, and in a few days I’ll turn on the autopot system.
