Do additive's expire? Also anyone using superthrive?

I was very into growing a few years back and really enjoyed the hobby (and the benefit of not buying). Due to a new job and getting married I put all my equipment and growing supplies into storage...

5 Years later, The time seems right again. I will be doing a 1000W indoor Soil grow for my first round. I'll be starting a grow diary soon.

Now here's my Nute question. I tossed all my liquid GH nutes a few years back but ended up keeping a few additives. Does anyone know the shelf-life of Tarantula or Bud Blood? I attached a photo (or at least tried) of them, been tucked away in a box for years, any reason I shouldn't use them? Hate to buy new if these are fine!

I just flipped to 12/12 yesterday, will be doing first nute feeding tomorrow trying to decide if Im going to add these.



Be safe.

I use superthrive, but i normally only use it during the veg stage. Forgot my specific reasoning but its mainly for better stem root development which is a veg stage thing. want everything towards bud site development so... ya know.. jus my 2 cents

I don't know if they expire or not. I also use Superthrive, for vegging only. It can delay flowering if used later.

Use just the cheap B1 for great root growth instead of thrive. You can buy a gallon of B1 for like $5 from Home Depot.
