pH go down in dwc

hey mate , thats perfectly normal in dwc. if your ec goes down day by day, it simply means the plants are actively feeding =) as long as ph stays table and the new growth looks healty, this is actually a good sign.

Happy Monday mate.. This is totally normal, at that rate it's only moving about 1.0 PH between water/fees change. Nothing to be concerned about at all.. Hope this helps, good luck
