That could be, 6.5 pH water every 2-4 days or when the pot size is very light to lift. Also, transplant soon to bigger pot.
my water is pH 7 and right now the pot size is REALLY heavy. Why transplant already? It seems there still a lot of space for it to grow in the pot... if I transplant I'm pretty sure it will die.
Soon- you wont harvest alot in a pot like that brother! Research some more... you need a cheap meter and pH up/down if you want to continue growing, its awesome knowing the pH- and not having issues. Dont transplant till you see hella roots by drainage holes, and its an auto, so when transplanting if you are going to, take your time and be careful. Peace
nvm the cfl wasn't enough, just switched to a mercury vapor light 160w and another one with 250w, which one should I use?
