Could be a bit of moisture build up and your lights just roasted that spot slightly. I wouldn't worry unless it starts to spread or you can see it from underneath. Happy Growing!

Blotched spots on fan leaves - calcium or fungus?
Started noticing some funny spots showing up on the big fan leaves. Light colours patches in non-uniform shapes-looks like it's spreading across a few of the big fan leaves only. Not sure if it's calcium deficiency or a fungal infection. No insects noted.

What happened to this leaf?
Strange brown spot on my girls leaf. Its just the one. To me it kind of looks like when you spray water on the leaves and the light burns it but I don't spray my leaves so what could this be?

Does it looks like N toxicity to you?
The strain is Jack 47XL auto. Leaf looks a bit too shiny to me but bud development is fine. For comparison, the plant on the left has dark/shiny leaf; the one on the right is the same strain, use the same nutrients but the leaf looks normal.

Red Stems on the fan-leaves!!
What is causing the RED stems on the fan-leaves of my plant. The Blue God is in week 3 of Flower. 2 other plants are getting the same diet and light and the B.G. is the only plant with red stems. How do you tell if it’s a deficiency or over-feeding? How can I turn this around?

Brown Spots, Any Ideas?
Anyone know what is causing the brown spots on the leaves? So far it’s limited to one plant, and it was closest to grow light. PH of soil appears to be normal, and I have not fed any nutrients yet. The water in my house is treated with Calcite/Corosex for PH correction.

Few leaves of my plants are getting these pattern with dots. I optimistically hope that it is just part of the aging of the leaves. Other leaves became yellow and fell also (maybe worth to mention). Is it normal? Thanks

Weird looking leaves
Regarding plant #2. Leaves seem really deformed. Very thick canopy, very short, abnormal leaves? And then what to do with it? Continue to grow? Cut it down?
