Exotic Genetix Chromatose in Living Soil

Unfortunately the middle plant continues to give me trouble. I have tried multiple things to help it out. I tried not watering for 2 days, then feeding with compost tea. The other two plants enjoyed this but the middle plant showed now difference. It barley even drank the compost tea I fed it, took very long time to absorb. It continues to get yellower every day. I think at this point even if I got it to bounce back, the bud wouldn't be quality at all. I am going to kill the plant and spread out the other two to give them more light coverage so I hopefully get a larger yield from the two remaining.
