Begonia plug plants not doing well

The good news is that mine are all growing well now including a few that had moldy leaves that i chopped off leaving just a tiny 1" stem. In fact one of those is flowering now and it's not much bigger and only has two leaves. I'm hoping for a late showing now but am wondering if it would be good to cut the flowers off to give the plant a chance to get bigger?

 

I think taking the flowers off can only divert energy to the plant, so that would be my choice. Try not to cause any "tissue damage" which might make a small, struggling, plant susceptible to disease
