let me guess...you took a puff before getting into your resivoir lol. i use as little as possible, but its MADE for plants, dude. call gen hydro, but id say its ok to do so. buy a dropper.
hehe, gardening under the influence is fun. as long as you are using plant specific PH chems and not spa/pool PH chems (I actually ran into a dude doing this at my local grow shop) you are good to go.
