I think I have a problem (check out pics)

I have had a similar problem before but much worse, it was due to my ph being off. However that was corrected and ph is spot on so I can rule that out, but check the pics out, this is what they're doing now. Any Insight on wth it could be??
Thanks

Check this link, looks like heat stress and/or nute burn: https://www.rollitup.org/marijuana-plant-problems/157345-have-plant-problem-check-here.html

The Heat/Humidity and Nutes have been at a consistant rate so I believe I can rule it out. However this problem seemed like it was going away, now it's back and seems worse then before...Any Ideas??
