They've grown a lot in just a few days. AK47 is showing off and GBK is trying to catch up.
Sweet growing!
AK47 really took off. As far as training, all you now have to do is look at the top 1 or 2 branches and make a choice - Do i want other branches to catch up? If the answer is yes, find a way to hold those top 1 or 2 branch tips lower than at least one other branch. Also, If there is a branch so low you want to give up on it producing flowers, remove that branch.
GBK may be a little behind, but look at those gorgeous fan leaves. She has ostrich feather fan dancer action going on - a beauty!
