Wind damage does look similar to heat damage! Look up pictures of wind burn damage to cannabis plants on Google! Usually if it is too much nutes or a nute burn the plants will look like they are praying with the leaves sticking up!
Um If leaves are sticking up last time i thought they want more nutes and maybe more light? I grow in bubble so maybe it is different than soil. Doubt it though. I think he has a deficiency. My plants curl down and I get red spots on my lower older growth which I believe is a deficiency as well. Nute burn starts on the outer part of the leaves. I think ur issue could be worse. If I get a moment tonight I will show you the older growth I have on my plants. The Large fan leaves look like shit so im sure you will be fine. so did you transplant them to new soil before u went to flower or what??? Please clarify when u can
