Bubblelicious feminized photoperiod

Slight hiccup with pH should be solved, new tester on the way. Temps and humidity are under control and growth of buds seems to be at a good average pace. Day 65 noticed three girls look really unhappy, leaves at the center/lower part of plant are drooping and yellowing, lots of lower leaves on one plant have died. Some leaves have dry patches and some pistils are turning orange. I then gave them a nute feeding and changed the ratio a little bit in case there is a problem there (FloraMicro has high nitrogen), and purple stems (though they have each always had a few) combined with these symptoms could be a phosphorous issue. But I think the yellowing and drooping was from underwatering (went 5 days between watering), and one plant was physically damaged because my fan fell on it last week. The sudden pistil color change was a shock but I am reading it may just be normal, maybe not the stress. They got more turgid a few hours after the watering. I really hope they bounce back. 😵
