Yer but you got to dilute and mix all three till ratio is either equal i.e. 5:5:5 or of a veg npk which is anything from 5:4:3 and up. 45 phosphorous is too much unless nitrogen was like 50-60 and potassium 30-35 even then this is a strong dose of ferts. Where are you getting all these crazy ferts from, seriously hard for a beginner to master a three part npk system, maths is getting hard here and hope you understand what you want to achieve, sure you wouldnt be better with just a soil veg and bloom and micro on top?
