This looks like it could be ph lockout . Try flushing your plant and see how she does

Hi! Check on "tobacco mosaic virus". The yellowish stains could be signs of it. Good luck!! :)

Kind of looks like very weird Potassium excess. Could be a form of PH lockout.

Yellow marks in leaf center and weird King Kush?
There seems to be some yellow marks developing in the center, this tends to be on the outer side of the leaf, especially during over/under watering? Could this be calcium/magnesium deficiency being that the water source is from reverse osmosis? Also, any thoughts about the KKush?
