Guys I need your help. I decided to start a DWC growing. First I add the nutrients to the water and then I check the PH. Ιt is usually above 7.5. Ok I say. Let's use PH down. I use general hydroponics ph down to make it 5.9-6.0. OK!!! But the problem is that if I check the ph after an hour I take a 7.3-7.5 ph. I 'm getting it to 6.0 again. After 1-2 hours the same. I have a 20 litres (5gallons) container. I tried with my pump on, my pump off my air pump on and off. With and without nutrients. The same results all the time. I also tried to another container. Nothing... So.... What The Fuck is going on? I don't have a ppm meter (...yet) but I think it doesn't matters for the PH.
I will try in a few days again with HESI'S ph down, but until then did you have problems like this??? What could I do...?
