Looks like light burn, but hard to tell. I don't see any nutrients listed or what your feeding.

Wilting leaves and copper spots? Save Me!
These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?

Hi all! I was checking on my plants and noticed one of them is showing yellow/brown spots in some the top leaves, only showing on 1 plant but I’m nervous it’s leaf septoria?? The plant is in week 10 and is my last pic on week 10 diary. Does anyone know what this could be? :)

Do you think the sudden yellowing of the upper leaves is due to the flowering, or does it indicate a deficiency instead?

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

These spots appeared on a few sheets this week. The leaves even twist. It's been a week since I added extra flower stimulators from Advanced nutrients. And I use Jungle Indabox nutrients. The problem did not affect the other plants. Can anyone help me?
