Has my tiger bloom gone bad??

Hello I'm afraid my tiger bloom nutrients have gone bad. Its darker than normal and there's this sludge crap in it. I think the cap might have been loose and let air in.. Is it no good now? My baby's need their water today and I can't buy any of this stuff till tomorrow. Please help. Sorry if I'm in wrong thread

The organic nutes i had left over from last summer went all chunky and darker. I just shook the crap out of it and used it like normal.

No ill effects. Worked the same. It was "General Organics"
