Only 1 Bud?

Hows it going autos will have a bit of growth in the first few weeks Of flowering I think it could still grow out a bit try low stress training if the stem is not too stiff you should be able to ties it down to the side of your plant pot to let the side branching grow out, you should get a lot more then 3 grams even with only one main cola but low stress training is the way to go for bigger yields, hope this helps goodluck ☘️
