What to Feed My Phals?

[Higgins23]

Hi all,
I have two very small phals and three large ones. With the help of everyone on these boards I was able to bring two of them back from close to death I've only been watering them, not giving any orchid food aside from kelp extract every other week for the weakest small gal to help with her root growth. I think I need to find a food with higher phosphorous if I'd like to see some spike growth and blooming, right? Any suggestions?
