Howdy Smiles, welcome to the forum and sorry to hear that You are having problems. I grow in two six gallon DWC reservoirs (currently on my 6th grow). Are You using R/O water in Your system? Some folks have trouble getting the pH to stabilize using R/O and/or distilled water. I use the city tap water, our water supply is from wells and lake, very hard water. I adjust the water and nutrients to a pH of around 6.0 and as the plants use up the nutrients the pH rises some what. The tap water (most likely the dissolved minerals in it) seems to keep a more stable pH level than the R/O water. You might try to make the water up (adjust the pH) a couple of days before You plan to use it so that it can be adjusted better before using it.
Good luck with Your grow.
