Help with nute burn

hey all i gave my haze 1cup/gallon big bloom about a week ago maybe more and this is what it did to my haze. My question is the way my set up is i cant put 9gallons of water through my pot to flush it, can i just feed it regular water and will it kick back(its got about 2 weeks left)? I havent used any chemical nutes just organic(bontanicare pure blend pro, fox farm big bloom). I recently watered them with plain water and it looks like it got worse within a few hours. Anyone think these will be ok? Does nute burn burn ur bud or just the leaves? Can i manicure around them? Any input = +REPS.

your best bet it to just give them water for the rest of their time if they only have 2 weeks left. Nute burn will pretty much effect the leaves so if you trim leaves that have burn close to the buds you will be ok. Burnt leaves will start on the outer part of the leaf so if you trim and feed straight water, the burn wont make it to the buds. Some leaves may become burnt close to the buds and it will be tough to trim that off on harvest day.

If you are using water from the tap, make sure you are using only cold as here are less salts in it, but ya you should definitely use plain water for the rest of the grow...Maybe try reducing the heat as well (raise the light).
