Try this:
Get a hold of 1000-2000 grit wet and dry sandpaper. Gently ABRASE the stem prior to cutting the 45. If you are leaving plant material on the sandpaper you are using too much pressure. I hold the stem down and pull and twist, seal with a tiny dab of rooting gel and make a nother hole off to the side of the big hole in the Rapid Rooter.
As far as the Bloom Nitrogen ratio, I have to agree w/ J.J.
When I clone into rockwool or do naked cloning (EZ Cloner) I use 1/4 strenth Bloom pH corrected to 6.3 - 6.5.
Mothers get Bloom and then just water 1 week prior to cloning.
Was working on a fogger cloner which did not have spectacular results, but using the sandpaper to abrase the plants cutical, had root and node like appendages up the plant where it had been abrased. Problem with fogger was it took too long to wean the plants off the humidity.
