I got a question for ya guys , I mixed up a new batch of water the other day changed and cleaned everything like I do every week. ph'd the water to 5.8 a few days later the ph is 7.45 I've been literally dumping ph - in and my ph isn't going down why ??? I'm gonna do a new water change later but was just curious why it won't go down it's almost like I'm adding ph +. The water is RO from the water depot never had a problem with it i almost never check my ph this late in the grow i can usually just mix and it hits around 5.9 to 6 and I'm good.
