DWC pH dropping quickly during flower

NASATrainerstarted grow question 5 years ago
Why is my pH dropping 0.5 every 24 hours? After reservoir change, pH is stable 5.5 - 6 for 4-5 days as I top it off with tap water, but then pH drops quickly end of the week. No EC tester, so I have to change reservoir every week.

water temps are probably a little to high and by the end of the week your probably starting to get a little slime starting. Makes your ph go whacked. Frozen water bottles or freezer packs in your water and keep it cooler and your ph should get a little bit more stable. Just adjust through the week when it drops.

What gm said, frozen water bottles, refrigerated water will help. In my experience some nuits claim pH friendly but there not and adjust high-low threw out the days. Just keep on it, don't have much longer to go on her. Looks good.
