Looks like a went a little over board last week with my roots organic bloom and super bat poop. Growing in a fox farm mixed soil my Hurkle strain.
I’m obviously watering extra trying to get some of it out. I’m about week 5 into flowering. Will the fan leaves recover and how will this burn effect my finished product?
Fox Farm stuff is pretty hot on it's own, as you have discovered. A copious flush a few times should help, although it isn't unusual for larger and lower fan leaves to yellow and die during flowering. Things don't look too bad, but the yellowed leaves will probably not recover.
