Brown spotting, yellowing leaves. Any ideas?

Hey all! Thanks for adding me on here! I’ve grown twice before this time but I’m stumped on my issue, mostly because I haven’t had to deal with it before and it seems I’m getting mixed answers all over the internet. Does anyone have any idea what’s happening to some of my leaves on both my plants? They started this about two weeks ago and I’ve been trying to solve it since. They have a regular feeding schedule of FF nutrients and I water every time the soil gets almost dry. I’ve done it for both my last grows and the worst I ended with was a little nute burn on the tips. Just trying to solve it quick before harvest. Any advice or answers would be awesome, thanks!
