I did say SLIGHTLY overfertilized, it's not causing your current issue IMO and no need for heroic measures like flushing. I just would not feed any stronger at this point. I agree with lazylathe, classic heat stress symptoms in those upwards cupped leaf edges. It's caused by too rapid water loss from the leaves. Air temp too high and humidity too low both aggravate the condition by increasing the rate of evaporation.
