Thanks for your help irish I called AN and they told me this
Thank you for your inquiry,
All of our products have a minimum self life of 24 months. If stored in a cool, dry place, away from direct light and excessive heat, many of them can last for much longer. Always shake the bottle before using it, if it has been sitting for a long period of time.
If there is a milky white precipitate in the bottle, which often appears in clumps or strings, this is nothing to be concerned about. A number of our products contain a protein based preservative designed to keep the products stable for a long period of time. If stored improperly, this protein preservative aggregates in solution, forming these precipitates. Upon prolonged storage under less then ideal conditions, which include, but are not limited to: excessive heat, HID lighting or freezing conditions, these white clumps turn from white to brown and eventually even black. As long as there are no issues with clogging drip lines, fogger, sprayers or emitters in an aeroponics system, the products should be safe to use, and can be strained to remove the precipitate if necessary. They should not hurt or damage your plants.
On the other hand, if the product looks like there may be a blue, green, yellow, red or a fluorescent orange mold like formation on the top, that would indicate that the product is indeed contaminated, and it should not be used. Return to the place of purchase with the original receipt to get a refund or an exchange.
I hope that this is the answer that you are looking for. If you have further questions please contact us via e-mail or by calling our tech support toll free line at 1-800-640-9605 8:00 am — 9:00 pm PST. If line busy or directed to voice mail keep trying.

So I then sent them this
I have been using it for 3 weeks how will it hurt my plants will they be safe for consumption? Should I flush the plants and use just water til I get new nutes?
They responded with this!
As I said, if the bottle looks and smells fine, it is most likely a simple protein based preservative, and it will NOT hurt or damage your plants. The plants should still be safe for consumption and you do NOT have to flush them or get new nutrients as long as everything looks fine.
Never really addressing the question I had about the possible mold
I contacted the place I bought it from and they will send me a new bottle as soon I send them my bottle and I left it on the kitchen counter when I left for work this morning lol!
