I recently purchased 10 white widow seeds and 10 Northern Lights from Nirvana, which I'm sure most of you are familiar with. Now, I believe I have very good germination techiniques with usually a success rate around 100%. I could not get a single one of the NL seeds to germ while sprouting 5/5...

I have a mother that just hasn't been healthy since day 1. She is now into her 15th day of flowering and here is a picture of one of her budding leaves. Am I over feeding her? Is it a temp/light burn? I had the HPS about 8 inches and backed it up to about 12 now. Any help would be cool.

While pulling one of my male plants, I noticed a strange root developement and am wondering if this is good or bad. As you see in the picture the roots, seem to have run down the outside of the medium and gathered at the bottom. I'm hoping this doesn't have any negative affect on the plant...

I just want to make sure that it is ok to trim some of the useless fan leaves that are wilting right now. They have turned yellow and dried out. Everything else looks fine though. Can I clip these? I've read that you don't want to clip fan leaves just below a flowering bud.

I've been vegging for 32 days now and my plants are about 10 inches high, with a nice set of leaves (5 or 6 nodes). Now I was thinking of isolating 2 out of the 4 plants-putting them on 12/12, to distinguish sex. Then eliminating the males, instead of wasting my time for a later result. Can I...
