I've got two plants, around 3 weeks old, on 18/6 schedule. They started developing buds. Why is this? I've attached a couple of pics, the second one has my hand in it so you can see how tiny they are. Feminized seeds. Could it be light leakage? I didn't think that was so important in the veg stage. I pinched off the buds, was that the correct thing to do? Thanks for any advice.
