Just started week 7 with my first grow they are zkittles og autoflowers in NFTG #4 soil with added perlite in a 2x4 tent kept at 62-78f and 40-50% humidity I use general organic nutes once a week starting after 3 weeks from quarter up to half strength and water every other day or when pot is light. Idk why they all grew at different rates I know now I should have done LST way earlier. I did a soil slurry and it came in at 6.9ph and 400ppm at 72f water runoff came pff at 6.9-7 too maybe that could be why they are looking so bad. Any help or advice would be greatly appreciated! I hope I didnt ruin them..

I grow coco, but pretty sure you want closer to 6.5 than 7.0 PH.
Yeah I should have forsure asked for help sooner, ive just been trying to figure it out on my own since week 3 when they started looking more yellow and showing spots on some leaves. The weird thing about the 2 really tall ones is I rotated and spun all of the plants every other day to different spots then those two got really tall despite that and I didnt know to do LST to keep them lower, then I got scared to keep them to close to the light and now they do stay on the sides lol I think the problem might be with the soil ph being 6.9 even though I water at 6.3-6.4 idk what to do to lower it at this point..
