Hello anyone have any idea what my problem with my leafs are im thinking maybe potassium def my tap water is 7.2ph very high in calcium maybe think might be my problem? humidity is very low 30% but was fine all last grow im useing dolomite lime to keep my ph stable as ive had a few ph pens not work for me and my other few grows have been fine only diffrance ive done is change from ro to tap water as it was to much work to do the ro.

Could it be as simple as nute burn or am I missing something?

I had similar leaf issues and never really nailed it down but suspected K deficiency too. I was using canna coco A & B at a low strength, about 5ml/gal.

I don't know where you are in flower, but if you feel you're short on Potassium, find a source of Potassium and add some to your mix...but don't over do it. If you only have a few weeks left in your grow, I don't think I'd do much except take notes and apply what you learned to your next grow. Good luck.
