Alright everyone I have a lsd and WW that’s week 4 of flower grown in ffof. Well I had to go out of town for a few days and watered before I left and they looked great but 4 days later I’m back and this is what I found. I know what I think it is but what is everyone else’s opinion.
Looks to be phosphorus deficient to me. If your feeding salt based nutes I’d give them a good flush to get out any built up salt caused from drying up.
Looks like that to me too
