I've got 2 floros with alternating full spectrum and cool white bulbs. Plus a 100 watt floro full spectrum. So I'm running 260 watts currently. I've been reading its all about seed genetics so I may have just gotten a bad batch.
I'm amazed at what you guys are doing in such short periods of time.
What type of soil, if any, are you using. Are you feeding them nutrients? What is your water source bud? See if we can nail down a solution for you.
