Hard to tell but if those are little white spots I’d start looking for spiderwebs

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!

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

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.

Yellow leaves black tips
What’s happening with this plant? After watering all my plants 2 days ago, one of them has been quite droopy and developed these yellow areas with dark tips. Is it a watering issue / heat / deficiency? Thank you

Your opinion?
Today flushing the wedding cake i was thinking that the problem was an excess of nutrients, but instead water was quite clean, around 1100ppm at the first drain, after several flushes water is now on 600ppm. I also raised the lights.. I still do not understand 🤔

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.

Burning Edges/Yellowing and Drooping?
The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!

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.

Upward curling leafs, burned tips, 2nd week of flower
So I'm two weeks into flower now and my leaves are getting burned tips (I'm guessing nitrogen deficiency due to the light green of the leaves or some lock out) leafs are also curling upwards :/. And some fading on some lower leafs. Using biobizz roughly 10ml each Any ideas

Light green leaves in color and burnt tips. Some leaves have brown spots.
Hi guys, can you please help me diagnose the issue. The plants are in BioBizz All-Mix soil. Treated with Bio Grow, Bio Bloom and Top Max from BioBizz. Also BioBizz Cal-Mag in the past week and 1ml of B52 (twice). A week ago I flushed and initially they were looking good.
