Plants are 5 days old and growing in coco coir. I'm using Flora Trip with calmag. Plants are 5 days old and I fed for second time today at little less than quarter strength. One plant is a much darker green and shorter than the rest. I'm using a 250 watt hps, 12 inches away. Any help would be appreciated.

How many do you have? What do the others look like...a few more pics would be nice. The first thing I will say is IMHO a 250w light 12" from a seedling...without an air cooled hood...probably not a good idea.

Oh, and breathe! Calm down...no need to panic at every thing that looks to you like a major problem. What strain is she? It could also very well (and even likely) be she is a pheno and this is genetic not going to kill her.

I've got 2 plants, 3rd plant didn't germinate. They are white widow fem from nirvana. I had the light farther away but one started stretching so moved it lower the second day. Here is a pic of their plant.

I was concerned that the plants where different colors when same strain. Maybe all is good tho.

I'm also growing in coco. I don't feed my seedlings until the second set of true leaves are on the way out, then I start feeding with 0.3 EC. I also have my 400w MH about 20" away from tops. If you wanna feed from the beginning, it's best to start with just 10-15% of the recommended dosage. Even less.

Ok, I just gave them there last round of nutes not an hour ago. I just flushed with ph'd filtered water and am just going to let them be for a few days. They seem to be coming along nicely. Don't want to screw them up. Thanks

Maybe a little phosphorus to help with root growth...?
I'm not sure cuz I grow in soil but....I think they look healthy to start
