|Your plants look VERY healthy!!! Yes...I would cut off the leaf of the H. kerrii with the black spot. You are growing good hoyas for your conditions (not much humidity, dry)...especially the H. kerrii which is close to being a succulent.
Why do you want them to grow more roots? They look very healthy!
What fertilizer are you giving them? H. pubicalyx 'Pink Silver' and H. carnosa both 'seem' to like growing in lower light than full smack on sun...and they enjoy growing drier more than wetter. I would feed them a balanced fertilizer with a higher middle number than the other two numbers. BLOOM fertilizers are good. Instead of once a month application, I would give the fertilizer 1/2 strength every second time you water. ALL hoyas enjoy aircirculation!!! not stuffy rooms. Hs. carnosa and pubicalyx are good ones to grow cool (I once saw a HUGE H. carnosa growing in an abandoned house in Taos New Mexico in the dead of winter. I don't think it had been watered in a LONG time.... Not a good way to grow them, but they do take cool/cold temps better than most.
I hope this helps....
