Burn or Deficiency

Coco should be 5.8 pH water

Are you sure your pH meter is calibrated correct

Fairly serious nutrient burn and related lockout/imbalance issues. At least you're close to harveset, so it's not THAT big a deal, the age probably seemingly exacerbates the imbalances as the leaves are depleted. But definitely lower your nutrients. Esp that botanicare stuff, I dunno what's in it, but since potassium silicate and calmag is typically sort of "safe", I'd guess it's the main culprit. And there's nothing wrong with feeding every day, it's just, use less if you do. Gradual feeding in my experience is ALWAYS better, anyway. Less pH related differentiation, "shock" so to speak.

Feeding micros? If I had to guess I’d say zinc deficiency just off appearance. Doesn’t really look like p deficiency to me but that just my opinion.

Definitely Nootz burn, check the EC of the run off. Feeding everyday is too much.

This is classic P deficiency. Could be cause of watterlogged soil. But I don't see as much clawwing down of the leaftips you would see with overwatering. If you have a high P low N feed, you can try a foliar feed w/o wetting the buds! If your soil is always wet, let it dry out for a while. If you have only days to go I would do no feeding, just flush with PHd water until harvest. Normal that late flowers eat their own leaves when flushing too. If you have couple of weeks, just some P and K extra. Good luck!
