Note all images where obtained on the internet I don't not support the use or cultivation of marijuana. Or any illegal substances this is all a part of a online fantasy life I live.

Buy Botanicare Cal/Mag get a PPM Meter & if youre using RO water add the Cal/Mag till it reaches 300....then split the remaining 300 PPM amongst your other nutes. Thats if you are using a 5 Gal DWC... I would def add Cal/Mag to your res. those leave might not go back to being lushes green though.

Couldn't you have picked some images from the internet with the LEDs off?
