Well so far I'm feeding them botanicare pure blend pro with a few products from that line it's basically botanicares advanced recipe and I also use molasses and have done banana peel teas but haven't used any nitrogen rich nutes no grow mix at all just bloom ph in and out seem to be the same which I aim for 6.3ish if I hit 6.5 it's high but runoff doesn't seem to really change by more than a .1 either way always feed and water to 10-15% runoff did a cal mag flush at week 4 but my bloom feed is a 1-4-5 and adding hydroplex bumps it up to 1-14-11 lol which I haven't gotten all the way up2 but idk where the issue is yet and still have seen some progression in the symptoms topleaves have started to look like they're tanning purplish before they actually start to look like they're crispy and brown spotting could it be too much light ppfd? Or could a deficiency/ excess or lockout lol be allowing the light to burn now?

Before changing ANYTHING, check your in PH and out PH. Would hate to diagnose as a deficiency meanwhile there’s already plenty of nutrients just a PH lockout. If PH, EC, and PPM are good then yes proceed with a little more calcium and potassium 👌👌👍 if they aren’t good then adjust the PH before adding. You might find that it is a simple PH fix. Do a quick run over and make sure everything is supposed to be where it is and how from there. Cheers man 👍

Your into flowering stage. That looks like too much nitrogen.. Try cutting down on nitrogen on next couple feeding ..

It is potassium deficiency, and go super light on nitrogen rest the grow. A great flower NPK ratio is 1-2-3. Good luck and happy growing 🌱
