"Cracked"??? You mean the bottles cracked? Seems odd as I've never had that happen to bottles of nutes that I've had for nearly 2 years. And if by "good term" you mean still useable/viable, I'd say yes since Ph down is a stable acid and bloom boosters should also be a straight chem solution that should remain stable for a while.
Btw if they "cracked" open then there may have been evaporation which would change the concentration/strength though. Usually the only nutes you need to worry about as far as having an expiration date would be organic nutes and anything with live micro-organisms, which tend to have shorter shelf lives.
That said, I tend to toss out nutes that have been sitting around for 2 years (that's liquid nutes, not dry nutes) on general principle, lol. I feel that if I'm going to put all this time and effort into growing my girls, why skimp on nutes and take chances with old products that might be compromised?
