I've heard vinegar is a last effort ph reducer, same with lemon juice. Most of what I've read advises against these natural acids in hydro. Get yourself some hydroponics Ph down (phosphoric acid best for flowering), but any kinda made for hydro should work fine. I like 5.8, but I usually just drop it to 5.5, let it slowly rise to 6, then repeat. Never change the ph more then .5 each day though, high chance of causing shock.
