When to attempt to make keikies?

[greenpassion]

Hi all. I recently ordered some keiki paste, and will attempt the operation of making kiekies from my phals. I had thought (from watching utube videos on line) that I should wait until the flowers have just gone by, and then go for the lowest nodes on the spikes to cut the sheath off and apply the paste. But now I just watched another video where this person was doing the sheath thing on a newly spiked phal, and was applying the paste much higher up. I have specifically 2 phals I really want to clone, and have been waiting for the flowers to go by. They both have been in full bloom since January!! Anyway, another problem I'm having is-there are no 'empty' nodes! They are branched spikes and fully loaded with flowers, and there simply are no nodes left to choose from. So not only do I not know WHEN to apply the paste, but where!!

I should add that the reason there are no noded left to choose from is because everywhere there are nodes there are branches coming out of them.
