@TheDane420 @Watt-Sun @T80gray @Oldguy ok guys idk what’s going on and it’s so frustrating some of my plants on top look great I would say 3 out of 5 but then all plants have red or purple stems and it’s only getting worse. I heard it’s from nitrogen toxicity. The nutes I use have 10% nitrogen witch compared to the bottled nite at 4% I’m guessing that’s alot. So I flushed for the 3rd time and went back to the lower nitrogen nutes. Also the undergrowth or larf is looking wilted and like it’s dying on every plant. Here are some pics. I’m now usings sensi bloom ph perfect, coco, great white once a week and open sesame once a week. The sensi bloom is part a and b ppm going in at around 750 and ph of 6.4 going in for the microbes comfort zone. Tops look great on 3 plants two plants are looking horrible. The last 2 pics ore the plants that I think are just dying no matter what I do. And remember all under growth looks bad. I did spray epsom salt to help with reddening and purpling of stems 1 tsp per gallon.
I use coco and led lights and i water every second day, when the husk at the top of the pot starts drying up is a good indicator to feed them hope this helps 
@Maddogg so water with feed every second day and water if u see the husk dry before that? What nutes are u using?
Just give them normal nute feed every second day is what i do you’ll get to notice that the husk up the top will dry a bit every second day, i take it you’re using leds as well? @ChaseV89
Ok no normal sinai bloom a and B with Cal-Mag every second day yes I’m using mars ts1000 and sonofarm sf-4000
That’s to high for coco . You need it to be 5.8-6
