Help please

Hi all,

My leafs have turned like this. I have looked for bugs but think I am being paranoid I.e the traps.. Can any one tell me what this is?

Ignore the temps. Its becouse I opened the tent. It's normally around 26c

Any chance you got nutes on the leaves? Otherwise, this noob will defer to the experts.

Some of those spots look like nute spillage, but others not so much. I can trigger rust spots like that by feeding excess cal-mag in a medium that doesn't need it -- essentially mimicking very hard water.

What's your water ppm without nutes, what medium are you in, what are you feeding, and are you tracking ppm/pH of your feeds?
