Why do the leaves of my plants have brown spots?
Why do the leaves of my plants have brown spots? I have control over all cultivation parameters except for humidity, which has been difficult for me to control and is currently high. What do you think?

Hi everyone, I’d like to solve the issue of the discoloration on my baby girl; I have given her new soul thinking I put too much worm casting’s in the mixture.

Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Brown, curling leaves?
I have no idea what's happening here but the girls are showing some kind of deficiency. Browning, curling leaves. I have two 100w led lights above them and I use an organic dry fertilizer, I recently brewed a compost tea to try to get nutrients to them

What kind of deficiency is this or is it light burn? Can provide more pictures since they are in a sleep period now. It’s this plant, strawberry banana one and the purple queen.

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?

I believe I have a phosphorus deficiency from lack of watering/early pH issues. I also have curly/dented leaves that can be seen in the close ups. Does this seem like a phosphorus deficiency or what else may it be?
