my setup consists of 3 5g buckets currently(waiting for 4th seed to germ) My plants are probably a week and half old they are starting to get their second set of leaves. I have added no nutes Im using a-ok starter cubes and put them in hydroton. I dipped the cubes in 5.5 ph'd water the whole time for germ and i rinsed the hydro off well to get the dust off. I have to change my water every day in my buckets My ph from tap comes out at 9 ph, i lowered it straight in the buckets to 5.5-6.o with distilled vinegar, already used all my ph down in leas than a week. After around 10 hours my ph raised back up to 9 in 2/3 buckets. One stayed at 6.2. I'm not sure what to do. When i have to add nutes they are going to get lock out or shock from ph change or something. I ordered hardwater grow nutes to use instead of micro from the gh trio. I'm using 4' air stones with alot of bubbles and blue lowes buckets. Need some advice quick. I can't figure it out.
