Curled leaves, dark green, light color between veins

Totallly 110% nitrogen toxicity. Too much nitrogen brothaa

I think you've a serious problem with too much nitrogen! If they were my ladies, I'd probably flush them and then go MUCH slower with your grow nutes as those are the ones that have the most nitrogen in them. If you swap out your grow nutes for bloom nutes after the flush (which they need since you say they're in flower), I think they'd do fine... bloom nutes have a much lower nitrogen content than grow nutes. I'm also a BIG believer in giving my ladies a dose of microbes once a week throughout their life... this increases the strength of the root system, helps avoid lockout and enhances the ability of the roots to take in the nutes you give them. Good luck... (and I LOVE your name... LOL!)

@LearnForgetRepeat I can see one major issue which is the fact you are not allowing the plant any rest . Despite what you may have read online all plants require a dark period it is important they get a break to recover from stress and any damage you may have caused . 20 hours of light is plenty . second issue you touched on yourself .... that PH pen needs calibrating or chucking away 0.1 of a ml is about all you would need to adjust PH I reckon your PH is probably at 10 now you added so much PH Up

Almost clobbered her. Hopefully she will have a full recovery, and she does look better 25 hours later 02-06 watered first time in 5 days. Was deliberately waiting for her to act dry and have a light pot. Then added 1 liter of water with 3 caps cal mag and 1 cap of grow big. At same time clipped a couple of fan leaves to ope bottom and a couple of bud sites. Also ph’d water for first time. Not at all confident did it right. Saw near a 5.0 ph in the nute water before adding it, so added 3-4 ml of ph up to get about a 6.0 That felt like a lot to add, so hope my meter was correct. Will have to get something to calibrate with. Within hours it looked like she was a goner with very droopy leaves that curled under pretty bad. 48 hours later she is about half better with leaves starting to stand up again. Still looks rough, with a couple leaves showing some kind of problem, and the remainder looking very green Soil was very dry again, so added half liter bottled water
