Reg, a seed has enough energy stored to bring that seedling into it's first set of true leaves. The plant will then need a bit of nitrogen, so I always use seaweed with N in it as the first fertilizer. It is very mild, has a lot of stimulating growth hormones and is just my favorite fertilizer. A seedling can be transplanted to its container also once the first set of true leaves appears.
The buds look great. You and BG are going a wonderful job. Have a great weekend.
