I have a plant that has been growing for almost 2 wks now and it just has the stem coming out of the pot and 4 leafs on the top and no side stems coming out, is that normal and if so how long does it take before side stems begin to grow? Ive read the Uncle bens toppings technique but really didn't understand it because of the terms they where using, if someone could break it down for me I would appreciate it
