Strawberry cheesecake

I had a ph issue... The plants started turning yellow and i thought i had a late nitrogen deficiency. It got so bad that the upper leaves started to burn. I raised my light and tried to adjust nutrients butbit keept getting worse. Come to find out, my ph pen was off. After trying to recalibrate several times, I decided to buy a new pen. Comparing the values of both pens, I realized that the old pen wouldn't recalibrate and was bad. I got the ph under control and the plants are getting better but the damage is done. The burnt leaves are pretty bad as you can see. They still smell great and don't have much time left so I guess I averted a a catastrophe. I will be buying back upstairs to all my equipment to avoid this issue in the future. I isolated one of the plants into another tent to keep in the dark for 48hrs. Will harvest that one soon.
