Fertilizers for flowring period

Hi,
I was using Schultz bloom plus (10-54-10) for my flowering period. However, it just gone from my local shops and I can't find it now. And i still have 4 more weeks to go. So I will be using Schults plant food plus (10-15-10) until I find a better solution. Maybe you could tell me what are the good fertilizers for blooming period? what numbers?

There's a good chance you don't need to feed again if you're using a decent soil. I've only fed twice with 1ml of nutes my whole grow and I also have about 4 weeks left.

I used max sea bloom my last soil grow and I've been using floranova grow on my current grow. Most bloom nutes will work fine. Low in N, high in P-K.
