Wrong stuff bro....don't use aquarium products on your plants...they are not fish! WHAAAAA???? Of course you've read all the sticky's and info here on ph already, right? Go get ph up or down for PLANTS, or use natural common household stuff to adjust ph. There's tons of info on ph here, if you bother to look...

You'll probably get more responses if you change that sig a little...just sayin...
