time to bloom! nutrient questions!

Hi...

I'm just about to switch to bloom and have a few nutrient questions

I have some bud candy and growtek monster bloom left over from my outdoor grow and was wondering if i could use them with other nutrients i bought;

Growing Edge Technology's (G.E.T.):
Let's Bloom part A & B, Power To Bloom, and Umph Power...

am i covered with the G.E.T. nutrient line? can i use the bud candy and monster bloom with the G.E.T. line? which would produce better results?

help me out if you can!

Ive got some off this for free today.

yes you can mix nutes. I've never used that line, so that's the best of help i can produce.
