They tend to twist or claw quite badly as if they are tasting something bitter

Looks more PH related in my opinion, although the rest of the plant is largely healthy- and it's hard to tell under the blurple light. Do you check your runoff PH? Input PH?

Anyone know what's wrong with my girl?
Can anyone tell me if this is going to effect my flowers? Should I cut these leaves out? What can I do to correct it? I left a pretty good description in week 7 of the battle with this plant.

Deficiency?
I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Flush or what to do ?
Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days
