Donated nutes need help?

Friend donated small amounts of different nutes to me trying to make sense of it. I'm growing in happy frog soil, 1000 watt light MH THEN HPS

with miller microplex

Any help would be great. Don't want to kill plants. need a starting point.

I think I might need more P for bloom???.

First is probably a veg formula, second a bloom. The third one, are you sure that's right?

Yes in sure. Any body else ???

Go to Peters website and read up on what nutes your using..
