Welcome
@kgonzalka.
I think we can rule out them being any variety of bromeliad. At least they are unlike any I am familiar with. You'll need to tell us more about their care. I know you tried Milorganite, which is simply a slow-release, nitrogen fertilizer. Apparently this is not a nitrogen problem. Have you tried dosing them with Epson salts, a good source of magnesium? What other type(s) of fertilizer have you used. Give those three numbers indicating the ratio. Coffee grounds won't help.
I expect someone to come up with a name for the plant. Knowing that will go a long way towards knowing what these plants need. You also need to go to your "Profile" and update your public profile so that we know where you are. Location is very important.
