not a problem, assuming that it is all the same *brand.* The only thing that changes is cure time --  In fact, one can intentionally mix two different speed hardeners (e.g. fast/slow) to change the cure time.

Here's  the FAQ on the Mas epoxy website that discusses that:

In fact, that's the only way to make medium hardener for Silvertip - mix equal parts fast & slow.

Gosh, I do that all the time ON PURPOSE.  With the MAS brand, you can mix hardeners willy-nilly for a custom cure time.  As long as the ratio of resin to hardener (two-to-one) never waivers, you're good with any blend of hardener.
