You mean store bought? If there is no date on it... And it has been stored properly, you know, not in sun etc... I would say a year or two after opening.

Thanks. I've had a 32oz. Bottle for about 2 years. Haven't been exposed to any harsh conditions or light but it doesn't seem to be working as well as I have hoped. Time for a new bottle I guess. Lol

I have a few plants that have this issue every grow. I'm sure it's not lack or over watering but I think it's either mag or iron deficiencies.
Had to ask about the cal-mag though. I've had it a while.
Going to get more tomorrow.
