Hi all i'm doing a coco grow at the mo but i am starting to get parts for a ucdwc. i got myself an air pump and thought i would stick it in my watering can for a couple of hours. so i set the nutes and ph (5.7) then put the bubbles in. went to check it a couple of hours later and the ph had gone up to 6. i thought nothing of it and added a couple of drops of down to set it back to 5.7 but it shot down to 4.8 am i missing something or does an air pump/ air stones fuck with ph.
