ive been looking everywere and noone seems to correctly sit down and write something theres only like one marijuana guide which everyone plagirises off and its bullshit. how could i lower PH? ( make more acidic ). its about 7.2 now lol im not nuting them today i watered them and started nuting 1/4. what could i put along with the water to make it more acidic? i use distilled 6.68 PH water. that meter is starting to slide towards 8 so im getting worried. no signs of anything bad on the plants yet how can i solve this? dont say bonemeal cuz i dont even know what that is and they dont have it here anything that is normal and can be bought anywere? like adding vinegar to the water of some salt or whatever. help would be appreciated
