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?

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

Nute burn or something else?
My middle and top leaves are yellowing from the tip and edge inward, is this the nutrient burn or another issue altogether? Runoff PH was 5.9 and ppm was 700.

Is this a Deficiency or Normal Flowering.
Flower 4 weeks. I have noticed thru flower approx 5 - 10 leaves/week which eventually brown, shrivel up, and fall off. Leaves seem dark and the stems are slightly reddish purple but potassium test on soil shows high potassium. Some burnt tips and claw down on upper leaves. PH6.0

Light burn or nutrient burn?
I have noticed that the tips of the leaves are yellowing and curling a bit. I moved the lights up 2 days ago and I honestly don't remember if this was happening before or not. It could be nutrient burn too, since I have increased the watering schedule, they are thirsty. While

Small brown points on older top leaves
1 week ago she started to get small brown points on older top leaves,and I moved her away from light to exclude light burn. Now there are a lot more of them. I flushed her 5 weeks ago, now she is getting full dosage of nutes. But these points look like nutrient deficient to me.

Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures). The box worked fine for several grows

Issues with leaves. Day 90 total, 30 of flower. Leaves have been getting more and more yellow the past week, with progressively more brown tips.
Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this

CalMag or PK issue?
What is she telling me? Before I was thinking of a CalMag issue (upper leafs have "burned" tips and get yellowish). So I added it to the reservoir. Is it CalMag or maybe a PK issue, that resolves in a CalMag issue? See my diary for more details.

Strange leaf shape, who has encountered this and what came out as a result?
1. Am I right that it was just overwatering? 2. Who has experienced the same thing? 3. What are the chances of growing a healthy plant? I appreciate all the responses, this is very important to me, thank you!
