Leftover bloom booster - use or not?

[ambersartain]

Hi,
I got this bloom booster fertilizer, I don't remember why, I guess I thought it would help them bloom. I'm honestly not sure how to use it in the first place. The bag says every 4th watering or something like that which makes no sense to me. I've read a lot that they don't help, so now I'd just kind of like to get rid of it and get something better.

Can I go ahead and just use a little at every watering and try to use it up? I also have some Miracle-Gro orchid fert. that I got when I freaked out that all I had was the bloom booster and I was going to hurt them. I know, MG, but it was the only thing that I could find at the moment and I tend to go a little nuts on these things. Can I try to use it up too, or what should I do? I hate to waste things.

Also, I have some mini phals setting spike (so cute!), a catt that's confused about the season, a tolumnia (also, soooo cute!) that was also confused and mostly put out new growth, but they just kind of stopped growing, an epicyclia that also put out new growths really late and now they're pale and weak (it's okay though I guess, the thing grows like crazy), and a dend that actually stayed on schedule. Oh, and the epi, tolumnia, and dend are mounted.

Sorry if I went into too much detail, I'm just not sure if I'm supposed to be fertilizing them differently. Oh, and can someone recommend a good fertilizer? I've heard dyna-gro is pretty good.
