Hydro nutes/additives expiry date?

[ConvexConepiece]

G'day all,

 

Been out of the game for a cpl years now however have started using my beloved equipment and tools again which had been neglected under the house for too long!

 

So I have heaps of left over nutes and additives from the last op and am a little scared of using it all again...

 

I've been using with no ill effects the remaining grow/flower A&B (all were nearly full bottles heh) so no problem there, however i'm worried about using the additives. I've got half a bottle of Microbial (root zone preventative) and ozi tonic/monsta bud aswell however I won't use them until I get some more opinions on 'how old is too old' for this sorta stuff?

 

Or should I just grab new stuff to be safe? it's been sitting in cool dark place for 2 years at the very most...

 

Tried searching the bottle, google and the company's websites however there is no expiry date so to speak.

 

Thanks all.

If you have been shaking them every now and then should be o.k. but if just left sitting hurl them.

Cheers Reverend,

 

They have been in a box which was occasionally moved so I think i'll start testing on 1 of the gals first and observe.

 

Fingers crossed I do no harm trying to save $50

Can you pour it out into another bottle and check how much sediment remains, if it has crystallised on the bottom best to get a new batch.

Cheers

Well the microbial is clear and is unable to form a sediment so still iffy on it, however I poured out the ozi tonic & monsta bud and they appear to be ok. Cheers
