Bud them already! They are going to be out of control. I had this happen before, and with stems that thin you are going to be in for a real pain in the *** job of staking them up every day until finished. When the buds get large they are going to flop all over like octopus tentacles. Use stakes and bud tonight if possible. You could be okay if your using a large light source, but if not lots of lower branches are going to produce next to nothing, hence a huge waste of veg time and space. Hope it all works out good and I would get as much light on them as possible for bud, not to mention a nice strong fan. Let us know how it goes.
