High density of foliage, sweat, high heat, humidity and most prob small lack of potassium... My guess.

Looks like water that dried on leaf. Unless it is all over I would not worry if this is only leaf like this.

Potassium deficiency?
Needing some help. I have this going on in my flower tent. They are in week 6 of flower. Of the 4, I have only one showing this bad. She seems to be locked out on me as well. Could this be a potassium deficiency? Seems to only effect upper fan leaves.

Before it becomes a real problem
Day 39. I realized that I was blasting plants with too much light as of the last few days. Made the switch to bloom nutes. Any ideas what's going on here. I want to fix this before it becomes a real problem.

What could these white spots be? They are slightly indented, not just surface spots.
Day 2 of Week 5 here for this auto. Here are photos of the top of the leaf and underneath it. Could it possibly be bugs? That's our hunch.
