Outdoor plant not branching out.

I put my plants out from seedling outside on may 30th and all of them are like 3 feet tall, but have no side branches. What should I do?

I've gotta see picks of this no side branching at all no tiny nubs thats just bunk man, if their three feet be sure they're in at least a 5 gallon and water em at least 2 times depending on the soil moisture, and give em the nutes they need to produce all those sugars to build a strong system if you've been doing that all I can think is thats gonna be one wicked nug to look at ha good luck man, oh and you could always try topping it, that and some bush master I couldn't imagine it not get bushier

Post pictures. Put it in a bigger container and top it.

Sorry for not posting photos, but i dont know how (lol noob)
