I have a few plants on the go about 3 weeks into veggin'. They're pretty small still but the biggest now has two 5 prong leaves. Every plant only has the one main stem with leaf sets coming off of it. I know that i want a large bushy plant so my question is how or when can i get some side branches? I have them under some cfl's and a couple of cool white 4ft flouros. I will be getting a 250 watt hps soon as well. What, if anything, can i do to get these branches.-keep in mind it is only a few inches tall with maybe 3 nodes.
