[Patriots781]

Day 36 So I checked my ph, the soil ppm was from 300-600and did soil test and my npk is fine,but most of them are around 7 inches and the leaves are mostly on droop and its really only the photoperiods my autos are doing ok,theres no light leaks,how do I find my problem,I have a co2 bag,temp is good,idk?the only thing I can think is maybe there not getting enough fresh oxygen but I have 3 fans one is a huge honeywell hepa carbon filter I did orrder a inline fan.

They look fine. I don't see any drooping, so you might just be seeing natural States of the plants throughout the day. They do take breaks to rest, so fans may droop a little from time to time.

Looks like you have, or had, some magnesium or calcium deficiency starting.

I don’t have any experience with LED’s to comment on specific red colors but, those plants look good to me.

How heavy are the pots?

I see what looks like some white dots on the leaves. You might want to check underneath with a Jeweler's loupe and make sure you don't have spider mites.
