I am running a basic hydro setup with a 2.5 gal tank and 3 inch net pots. My nutes are FF grow big and super thrive. I changed the water the other day and added the first full dose of FF which was 20ml and 3 drops of super thrive. When I checked the ph it was red (3.0 or lower). I poured (a little) ph up in the res and rechecked. Seems like its right where I want it at about 6.5 but my water is cloudy. I can't even see the roots anymore when I look through the water. If my plants are happy and the ph is good should I be worried about something else?
