Hey growmie,
It looks like you have the start of either a Potassium Deficiency or a Magnesium Deficiency. Those are the only two things that could create those brown spots in the middle of the leaves.
Hopefully, this was helpful and remember ..."Happy Growing" and "Free your mind one puff at a time".

Browning leavesMy leaves are showing some brown spots 5 days post transplant. I also increased my light from 30% intensity to 80% intensity. I have them 18” away currently. Am I showing signs of light burn? I have since turned the light back down to 50% and I am not on a 18/6 cycle

Bud rot? Mold?My plant is a bit problematic ("quick one" Auto from RQS, outdoor balcony grow).
I'm a bit worried that I have to throw it out, therefore I would like to ask for your expert opinion. :)
1. Is the "brown stuff" on the top bud "bud-rot"?
2. Are the "more intense white spots" mold?

Brown/yellow/purple leaves inThis started out as brown spots on big fan leaves and has turned into what you see on the pictures. I've been ignoring the discoloration until I was greeted by some wilted, dead leaves on plant #2 today.
I'm not worried at this point, just really want to know what's happening
