Hey,

For adding the PH up / down, add VERY little at a time, maybe a few ML. Its potent stuff! I use a straw, dip it into the PH solution * depending on which I need *, and use my finger to plug the top end. Works as a small dropper, and I don't often overshoot my PH mark.

Good Luck!

Hi all im a new grower just starting out and I have a 8 bucket water farm with a 8 gallon texas controller and a 17 gallon reservoir just to let ya know what im working with. I have been searching the internet plus these forums like a madman and I couldnt find what im lookin for. The usual pH range from seedlings and vegging I heard is 5.8-6.0 but the confusing part is how much ph up/down do you measure out to get it back to that range from a high alkeline or from a high acid.
