Can You Mix NUtrients from different brands?

Can You Mix NUtrients from different brands?
Where i live no one sells series off nuts, that i can use for a my growing cycles...I have 2 choices,

1) i have a bit of left overs from a previous grow and the ,local market can supply few brands.....(need your opinion on what goes with what and when is best to give each product list is below)

2) I can order online and will cost me a fortune but its ok they are worth it (need your professional opinion on which brand to buy that keeps flavor and taste of the plants )

One more question, if i had nuts for over 4 years can they still be used?

Nutrients on Hand:

Mir-grow quick starter 4%-12%-4%
Mir.grow Blood meal powder 12-0-0
A french brand 5%-6%-7% with other elements see picture
Canna flora 2-2-4
canna PK 13/14
Schultz all purpose feed 10-15-10
Alaska 0-10-10

I have the whole set of HESI products but they are 4 years old ?? can i use them.?

sorry for the side pics ..i did rotate but they came up tilted once uploaded

you can mix different nutes, but you have to have a good nute line setup to do that. the only thing i see good in the pics is the canna stuff, if you are serious about this, i would order a kit of nutes. I used foxfarm with good results when i started growing. I wouldnt use anything over 1-2 years old, think about what your doing when your end product is done. I only use good nutes if i myself are consuming or smoking this stuff.

kush is right....i bought g.e.t nutes and cost me hundreds of pounds ...theyre a bloody nightmare to use and jusst wish id stuk wiv canna that id used b4...now i stuk wiv it all...

THANKS for the advice , very serious actually will be shipping a good line for sure, heard about fox farm and earth juice . will choose one of them i guess . follow my grow i am in 4th week flowering
