Yesterday I brought home 5 slush plants. I'm useing a bubbleponics Ina 25 gal tote. Mixed first week nut to the gh chart ph was around 6 last night and this morning it was around 7. I have gh ph down. I added 2 caps of ph down in a half gal of water and added it in. So is this ok to do. It did bring down my ph. I'm wondering is this going to be a daily habit
