The plants in HPS are more mature than the two week older plant in LED. Because of the slow development of bud in LED, as a rash measure I'm switching the time to 12/12 and have introduced a halogen bulb (60w) for more spectrum. See if these steps will prod the plants system. Any comments are welcome, of course.:beatdeadhorse:
P.S. ~ Edit: Also added the UV-B lamp. (20w CFL.)
