hey guys, just an update on my grow. almost into the 4th week of blooming, and started to notice some of the top leafs were getting a little burnt on the tips and curling up. i adjusted the height of the light. but not sure what else i can go. i am using the DNF supplements (Bloom A,B, Gold, Black Carb & Bloom Fortifier). using the recommended amounts in 3 Litres of water per plant (2.5 Gallon Pots with ProMix) on every 4th day. i am getting a little water runoff. the burning does not seem to be getting worse, just wondering if once a leaf is burnt if it will ever recover.

anyway advice is appreciated.
