Do they grow on the tip end of a spike on a Phal, or is it separate from a spike? If they are on the tip end of a spike, what effect if any, would they have on the buds?
In my experience you either get new flowering growth or a keiki, I've never seen both on the same stem. The buds or the keiki form at the node, usually more than half way up, which is one reason why I never cut the spike all the way back until I see what it's going to do. - Ian.
