This is paranoia speaking.... I mixed up some Tmax developer about five hours ago (diluted 1+4) and then got pulled away and couldn't use it. It's been covered tightly and left at room temp. Think it's still OK? I'd probably just toss it and start over, but I'm nearly out and need all of it I can to get through a backlog of film tonight. I'm several hours behind schedule at this point. Yuck. Your thoughts?
