Nute mixture?

Wat would be a good nute to mix with my big bloom for my outdoor greenhouse plants thats safe for the plant and a lil better in nitrogen than the big bloom seeing as tho big bloom is so low

Can anyone help?

well since u started using fox farms line like big bloom, start using grow big with it since it has a lot more of what u need. its 6.4.4. so N will be covered. i dont know what week u are in growing but if u are at least in week 3 start using kangaroots and microbe brew. this will help u a lot in your garden. im not a big user of fox farm but i know these are what u want in the line
