what are you fertilizing?

I use schultzs orchid fertilizer at half strength. One thing you don't want to do is over fertilize Broms or they will be bright green, they do better underfed colorwise.

what broms are you fertilizing? One fertilizer does not work on all broms

I realize you are probably not asking me, but I have mostly Neos, a few Aechmeas, Billbergias, and Crypts (I don't use it on the Crypts). I would not use it on Tillandsias if I had any.
