It's cheap and you have at least 5 weeks left, likely 6 or 7. Get some more. A pH of 7 will severely affect what nutrients she can use. If you can't get buffer, you're better off catching rainwater and using that (it's usually more acidic).

Hi!
You can use white vinegar, apple cider vinegar and or lemon juice for ph down.
Use small amounts until you find the right ph.
Happy grow!!!!

it should be, but you can always use lemon juice to lower ph in a pinch, i would suggest keeping your ph where it should be, also if you dont you should be ok until harvest but you do have a little bit to go for that

Small plants, 3 gallon pots, and Pro Mix HPHi all,
I've just moved baby's from solo cups to 3 gallon pots. I'm using Pro Mix HP.
