I add vinegar to pH balance my water, is this okay for flushing the last two weeks? I don't have anything else going into the water.
I'm not sure what you're asking. Is what OK? Using vinegar as you have throughout the grow so far? Yes to that. Have you actually flushed? You don't flush for two weeks, you flush for maybe two hours and then you have a two-week period of no feeding after that.
Sorry... I'm harvesting in two weeks and I know your suppose to give it straight water (no Superthrive, no nutes, nothing) when watering. I always used vinegar to get my pH balanced throughout the grow, but I just wanted to make sure it was still ok to add vinegar during these last two weeks before harvest. I've flushed (leached) a few times during the grow to get rid of salts, but I don't know anything about a two hour flush and two week period of no feeding???
