Should I Use?

Really Mr Chevron, should be fine, you wouldn't risk it, but you would still use it?? Which is it? 😵 Unless it has boiled, which could/might/maybe change its chemical composition, having the bottle warm up would be no different than leaving it in a warm garage or shed over summer. Not to mention travelling in the trailer of a truck for days on end, across deserts and mountain ranges, across vast plains, high into the Rockies or through ............................. I think we get the picture. I will now take my meds and have a lie down. Sorry. ..... ... .... Organoman.

Should be fine to use, but honestly, I would just buy another bottle. Calmag is tricky stuff and can cause all sorts of issues, so I wouldn't risk it. I would still use what I have until the new bottle arrives though. Maybe it's just me...

Should be fine. I can't see how it would change anything unless it has boiled.

Hi! I don't think that's healthy. But I would reach out directly to the manufacturer of the Calmag product for a correct answer. They will know best. Because we can tell you what we think, but we can never be 100% sure if it's really usable. If the manufacturer is one of the nutrients on Growdiaries, you can contact them via an instant message. Good luck! 🌱
