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

When to use terra aquatica ripen? Wait until they look ready to harvest or when they look like they will be ready in 2 weeks while using ripen?I'm coming to the end & I think they need a few more weeks at least, but I may be just kidding myself, thinking they're gonna double in size.
I'm gonna use ripen for the final 2 weeks with a 48h flash clean before & after, so should I start now or wait for more amber trichomes?a year ago

Soil pH not adjusting even after watering pH water.So Far I've been 6.5-7 pH water, & organic ferts BioThrive Grow, Bloom & CalMag. The soil pH doesn't seen to go any below 6.5; even though I've been feeding 5 pH water to make it lower. Why is this happening? What to do? Does organics in the soil auto-adjust the pH all by itselfa year ago
