pretty close like 5 inches from a quantum board led, def too bright for veg. I turned the light all the way down going to move them tonight ran out of headroom.

Could be ph i had to use tap instead of ro this week because my filters were bad. I usually dont ph as my soil has buffers.

forgot to mention I had plants in front of these ones blocking the wind last week so they are getting more light and more wind. they were good last week.

I'm in no till organic what can I add for ca? i figure my compost must have tons of that so maybe the ph is just out of wack.

Its russet mites. The pinch at the base of the fan blades where they attach to the leaf stalk, the twist on the young foliage and that curl on the serration tips are what I'm looking at. Large grouping of russets look like a rust to the naked eye, but when you scope them its a teeming mass of hideous insects.
The first time I got russets I was certain that it was nutrients for the first couple weeks too, the early warning signs can be similar, especially to potassium.
