one week after putting plants in dwc starter plugs turned white?
I just started with hydroponics and currently have a dwc setup. I have a few concerns one of which is that the starter plugs have turned white. I am using General Hydroponics maxi grow at about 1 teaspoon per gallon, maxi-cal 1 teaspoon per gal, and plant success mycorrhizae. Could it be that the mycorrhizae is turning the starter plugs white or do i have another problem? Also my ph seems to swing overnight from 5.5 to 6.5+ I cant figure out whats wrong with it. Any input would be appreciated.
