Hi guys,

sorry I should ask this sort of question; again.

But I'm pretty insecure if it comes to chemicals because I do not want to miss a 4X5 negative because it was not okay.

Anyways. I have chems mixed up and stored in black collapsible since 10 weeks ago, only used one.
Today I'm shooting again and want to develop them tomorow with those chemicals.

Am I safe to do so?

Thanks guys!
