These were planted 4 weeks ago in a mixture Fox Farms Ocean Forest/Destiny Organics Dark Matter and amended with Gaia Green before planting. They are Fastbuds Zkittlez except the back left which is Canuk Cheese(which has been having heat stress issues). I got worried about the soil being too hot so i switched to the General Hydroponics trio and calmag a couple weeks ago . Using a Phlizon cree cob 3000w led in a 4x4 tent. Lights were at 34" for germination and now at 24". I've been trying to follow the VPD chart but at the start of veg i noticed some fungus gnats so i have lowered the humidity to 50 and i've been treating with Purecrop1. Was at first growing 24h but switched to 18/6 about 2 weeks ago. I've also been watering with water i sit out for 24h and ph to 6.2

If I walked into this in my tent, 1st I'd get rid of those really bad leaves down low. Leaving at this point is asking for more issues.
2nd, the curved, clawing would have me checking the soils pH. 2 tablespoons soil mixed with 2 tablespoons of the water you use to feed. Let set a couple minutes and test (carefully) with pH meter. Am guessing that as the plants have used nutrients in your soil mix, the pH of the medium has been dropping and 6.2 is already on the low end for watering in soil, which could, exasperate the problem.
Edit: I ran fox farms for years, dropped them about 2 years ago now, issue was pH drift mid flower.
