We have young plants starting to yellow from the bottom up and an older veg yellow from the middle throughout and dropping leaves rapidly. They appear to retain green veins until they don't, yellowing from the outer edges, sometimes just fading through the entire leave. Some leaves have browned curled parts, some not. These are DWC, using BC nutes, PH in the 5.8-6.4 range, temps ambient in the 83-87, nutes are 78-85 degrees. Using air stones and roots look decent.
We've had this issue in the past. Some plants affected and some not at all.
Any ideas! Thanks.
