Check the underside of the leafs with a microscope and look for bugs like spider mites. When they feed on leafs they eat the chlorophyll and leave behind that same look on top of the leafs.
Zandor Reviewed by Zandor on . Quick DWC question I have 18 plants going, only one in hydro, all 18 of the plants look great with the exception of the one in the hydro. It has always been a pale green compared to the rest of my girls. Ph, temps, and humidity are all right on. Am i being paranoid. I read somewhere that hydro tends to be a little lighter in color, however i am curious to get a live answer. I am using AN two part for nutes, light feeding. Thanks in advance. Rating: 5
