So this started 3 days ago. Its gotten a bit worse. Only 2 plants exhibit this and only the top canopy. Everything else underneath is fine. I thought it might be my fluence. Too much light is cooking them but the rest are absolutely fine and happy.
What could cause this?
It's most definitely heat stress 89 degrees is a bit on the hot side my room
goes between 70 n 85 (when it's in the 90s outside). If you were early veg n they came from clones n it was the bottom I would say it's normal especially if you use an alcohol based cloning product like "
dip n grow" bc it does look a little like a chemical burn that you can get from miracle grow too. How often you water/feed them? Mine I have to water every other day sometimes 2 but mine I think it's the plants being too big for 3 gallon
smart pots. Your leaf issue is definitely heat related. Have you giving them a form of
silica blast? Lots of companies different versions of it n it will help with all kinds of stress issues especially heat related. I use the "Go" line from
general organics for veg n flowering but in flowering mix in the "snow storm" line oh n also use SOS through my whole grow even in my bubble cloner. These are mine that I have flowering now a little over a month pots way too small imo hence the fact of them needing water roughly every other day.
