Looks like a lockout caused by too much PK. Try cutting back on the tiger bloom. The spread should stop although the spots probably won't disappear ever.

Always diagnose before you react. Diagnostics 101 Check your runoff ph and ec levels. The two most important factors in a grow. One of thos 2 off and your plant starts to suffer. Find out what your nute levels is at the roots. If its creeping up more than what your feeding at it is getting overfed and It's causing lockout. If the ph is out then that also causes lockout. Nutes to low and ph is ok, then you know it is a deficiency and not lockout. Cheers

Brown Red Round Spots on 4-5 Fanleaves / fungus ?Hey folks, I have this issue with one of my ladies. There are small reddish-brown spots on 4-5 fan leaves, while the other plants don’t have anything. What could this be? I think it’s a fungus, but I want to be sure and know exactly what it is before I start treating it.
