Are my nutrients still good?

I have 3 bottles of GH Nutrients (Micro, Grow, Bloom) that have been sitting on my nutrient shelf for maybe 2-3 years and was wondering if they were still good to use? It still looks good to me (ie ; no visual salt/crystal deposits, etc.), and wanted to go back to this line for the next grow. Didn't want to be wasteful and purchase new if this is still usable.

I just used botanicaire pro grow i havent touched in 2 years. I was wondering the same thing but plants got a nice pop from it so id say go for it.

good as gold, brother. you can bubble your nute water for 24 hours to charge it back up with micros and oxygenate it, for good measure. throw a tea bag of garden soil in with the bubble, and you will have a vibrant pre-made ecosystem to introduce to your medium. the air will help oxidize any complex acids that may have formed into simpler ones. and always check ph.

Awesome, thanks guys!

Ya I go back and try nutes I bought years ago that I gave up on, thinking maybe I know more now. No problems so far.

No problem use em.
