I'm growing 2 plants from bagseed. they are about 2 and 1/2 weeks old and look pretty big and bushy for their age. One of them has a big thick stem compared to the other, but both look as if skin is peeling off of the stem up until the first 2 leaves. It almost looks like they're shedding the skin on the stem. I have't been used nutes yet, so what's the deal!?
