How do i know if my nutes are still good??

I looked for this question but, alas, could not find it.

Here is my specific dilemma:

I stored my nutes in my garage, and about six months later I go to retrieve them and notice one leaked onto an unused surge protector and corroded it beyond belief (major nute burn haha)

BUT I wasn't so worried about that as I was worried about the crystalized nutrients in the bottle. Even the sealed one that didn't leak had a "solid" block floating around.

Is this anything to worry about and can I just shake up the bottles until it breaks down and still use it? Or did my terrible foresight doom me into wasting money?

Just shake it up again, if you let it sit for long enough the disolved material starts to crystalize around the sides of the container lol nothing to worry about

Nothing to worry about, just do the shake treatment and you should be good. As long as the nutes arent 10 years old, good to go.

WHEW! Thanks guys, I'm strapped for dough and was seriously worried about this one.
