Good Earthtainer fertilizers for Canadian tomato growers?

i'm trying out the actinovate-biotamax-mycogrow (ABM) this year and so had to look for fertilizer with P no more than 4. found this one at Rona
http://ronaeco.ca/en/rona-eco/8/32/20095055/. a lot less money than the fertilizer i'm supposed to use in the water reservoir of the SWC i'm using.

ingredients: crustacean meal, natural potash sulfate

analysis:
5% total nitrogen (N)
3% water insoluble nitrogen (WIN)
2% available phosphoric acid (P2O5)
2% total phosphoric acid
8% soluble potash (K20)
9% total calcium (Ca)
0.5% total magnesium (Mg)

anything above that should be of concern?

opening the greenhouse door greets one with a rush of powerful efluvium! :-]

the tomato plants look happy enough.

although i'm not sure if that's due to the fertilizer, the ABM, worm castings, kelp meal, filtered water, or...

going gangbusters on amendments in hopes to improve the taste---last year was a bumper crop year but mostly spitters.
