Upward Curling Brown Leaves/Nutrient Lock Out?
I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light. Leaves are curling upward and browning. Not crumbling yet but look like they will be soon. Both new and old growth is being effected. Maybe the Mineralized Phosphate was too much.
