10 Gro with 5 and 5 of the other two will be sending your K very high for plants not even close to full flower, so I'd advise against it. You may notice that Bloom isn't even in my calculated numbers.
As a matter of fact I would never use the Bloom, since my full flower (post stretch) recommendation would be:
12.5ml Gro
6.9ml Micro
1g epsom salt.
