Ok so I have a 2.7 x 2.7 grow tent. And I have a 10 reservoir for the flood and drain. I have a 400 hps along with a led for supplement. I just got the whole line of advanced nutrients and I was running according to their formula on their website but I figured that was way too much so I dialed it back to half dosage. Every time I do a res change and add fresh nutes the water gets cloudy and murky. I'm trying to forgive out what is causing this. I am using sensi bloom a and b along with bud candy, b52, voodo juice, rhino skin, nirvana, cal mag, big bud. Also I can't tell whether I have an over nute prob or a cal mag def.
