What could be causing this?
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Nute burn (Added nuts to supersoil)
So, I added unnecessary nutrients to my super soil and end up with nute burn, I Flushed until ppm was 1100 it was over 6000, and since i've been dealing with yellowing and curling leafs, brown spots and well it's all going down so quick. Any idea how to fix this. I'm lost.

Fan leaf deficiencies during flower. To cut or not to cut?
Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?
