SeedlessOne, Pinch the very top out so as to promote side branching. You might have to top the upper branches afew times to get the side branches to come out good. I have a strawberry cough that just showed a few white hairs. It looks almost like yours. I just need to top it. When the side branches come out wait till you have a good bit more than 2 sets of leaves then take a cutting. In the end you will have a mom that has loads of cuttings to take.Shorter plants that are close internoids take longer but will get there.
This is a method from phototron to promote as many bud sites as possible but it works better for getting loads of cuttings.
