Hi everyone. I have noticed that on several of my hot pepper seedlings, the leaves are turning purple in color. I have browsed the forums here and from what I've read, this appears to be a somewhat normal response to placing seedlings underneath fluorescent lights. My plants are underneath two light fixtures, each containing two T12 4-foot long 40-Watt Agrosun full-spectrum fluorescent grow lights. I have the lights approximately 3 to 4 inches above the tops of the plants (from what I've read, 2 to 4 inches is the preferred distance). From the posts I've read, this usually happens to plants that are underneath the more powerful T5 lights. Has anyone else had their pepper leaves turn purple underneath T12 fluorescent lights? Of the 7 varieties of peppers I am growing this year (Cayenne, Datil, Chocolate Habanero, Golden Habanero, Bhut Jolokia, Butch T Trinidad Scorpion, and Anaheim), only the Golden Habanero, Bhut Jolokia, and Butch T Trinidad Scorpion plants seem to be affected thus far. Has anyone experimented with T12 fluorescent lights and come up with a perfect distance to place the lights above the plants that would allow them to retain their green color, while at the same time provide sufficient light intensity for normal growth?
