Yo yo growing in a hot, dry environment Green-House, not ideal conditions. 90-92 degrees low humidity 20-30….eeek!! Leaves have tiny little holes some have yellowing middle edges of leaves. Few rips in leaves. Looks like a stressed plant from environment but checking in on your thoughts?
ec feed 2 with cutting edge, RO water extra cal-mag.
bugs?
Gnats, over water and calcium….trifecta film festival.
I wish I could see the whole plant, not just the sick examples.
First two shots look like physical damage caused by fan or gardener. Third photo maybe calcium, but given that you have low humidity and are feeding calmag I think probably not. There are some suspicious spots there, maybe thrips, mites. Got any sticky traps indicating pests? Any IPM going? If not, I consider some wettable sulfur sprays weekly to keep bugs down until flower onset, then switch to a mild Dr. Zymes, Nuke Em, or a tiny bit of Bronner’s soap to wash off sulfur at the start of flower.
While you still have time, Clean your plants welllllllll with water and slip a nice prophylactic on them. Wettable sulfur is my favorite outside. Having that layer of stinky yellow always makes me feel safer. I hose my floor and walls every day in greenhouse for humidity boost in morning. Washing your plants a lot creates lotta humidity too while pissing bugs off at same time.
