you should be using tiger bloom right now. the tiger bloom is 2-8-4, the B.B. is 0.01-0.3-0.7. you need more P in flower.

i started flowering yesterday. I feed 3 tsp G.B, 2 tsp B.B, 1/2 tsp T.B., 2 tsp Liquid karma. 1/4 Super Thrive. I just followed the fox farm feeding schedule. I going to stop with the G.B. next feeding. I stop feeding S.T yesterday because the guy at the hydro store told me that its has too much hormones or a certain hormones that can interrupt the budding.

The leaves won't recover from the burn. all you can do is continue on.
as for those burns, don't mist with lights on. the water can act as magnifying glass and burn your leaves even worst. plus its in the flowering stage, i'm scared to mess with the buds IMO.
