ok im trying to grow in soil and the water in my area is to high in PH, around 7-8. what is the best way to lower the ph? i tried using white vinegar on my baby a few weeks ago... but she ended up getting some nute deficienies and i had to pull her. i now have three seeds that i just put outside and i want these bitches to flourish. what can i do? would lemon juice work?
