My top fan leaves look like rust! Help!

My 11 week White widow auto started getting these brown spots that are looking like rust now but only on the top leaves.

It looks like you’ve been getting all kinds of spots for a while. Are you feeding it anything? Or did you get to week 6 and decide to flush for 2 weeks because the website said it’s an 8 week strain?

We need more info to help bud

Yeah, I've been feeding it nutrients. Micro, grow, Bloom and calcium magnesium. Feed them everyday with pH balanced water. Always aim between 6.2-6.5. this is the feedings per week from week 8 till now week 11. The ratios are in milliliters for a gallon of water.

Had this pop up on my Norther Lights run, had been letting my pH drift at the high end for several days (6.3-6.4). Pulled the pH back to a max of 6.1 and it stopped progressing immediately.
