Hello, looks like PH Problems. If the newer leafs okay and the symptoms stopped no problem. If there will come more leafes in the middle and lower section like this on the picture i would check PH.

How's the quality?
How would you rate the quality of these plants? The dark brown leaves have me self conscious of the roots situation. DIY supersoil mix recipe here: https://pastebin.com/pbxMZysq I've added more dolomite & guano as topdressing and fed liquid calmag and potassium during flowering.

I have a few brown spots and slight yellowing on a couple of my 3 finger leaves and even some on a 5 finger (#2). It seems to be getting worse every day. I have done a lot of research to find out what it could be but am very confused. Any ideas? Pictures from 2 different days.

First time growing/Need help in late flower
Over the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

Leafs with brown spots
The leafs on my plant are showing brown spots. Could be nutrient burn or nutrient lockout? Not sure at this point. It started a week after blooming.

What is this brown spot?
What is this brown spot? 18” from light. Just fed about 10 hours ago with dr.Earth 1-1-1 liquid solution watered in with 1/4 gallon of water. It is the only spot on whole plant. I know the temps are high. Wondering if it could be something else.
