Ok Humboldt,
I just got do reading your thread and J. u asked a ? about the different types of light and I don't think you got an answer. From what I have read the daylight cfls are the best for vegging, and the soft white a few cool white are good for flow. I was able to get a daylight 65/500w flood system for $9 at costco. It came with the bulb and houseing w/a plastic lid which helps with heat. The box says it has like 6300lum, but when I look up the Man. on line they say it put off 9000 lum. humm its 420 be right back. Ok thats better. always good to think with a clear head.
I saw the little yellow/brown spots, they don't look like much. mabe a little nut burn in that area. But your plants look good. what r u using to test you ph? that could be the issue aswell.
Take a look at My J. I have added a lot more pics. they have now been flow for 10 days and you can see the little buds poping up.
GLG
Logan.
