Mixing nutrients and then leaving them?

Hey guys,



I am going on holiday for 2 weeks and one of my siblings will be feeding my plants.



He doesnt know anything about growing at all so I was thinking of making it super easy for him by pre-mixing my nutrients then putting them in sealed bottles for him for the 2 weeks so when he has to feed them, he just picks up one of the bottles, opens it and pours it into the soil.



My question is some of the bottles will be there, pre-mixed for upto 2 weeks will they be ok?



The nutrients are biobizz organic so I know if you mix them and leave them in an open container they will go weird and start stinking.



But is this the same if the bottle is sealed and no air is getting into the mixture?



Would love if anyone could help me with this tricky subject!



Thanks,



Peace

So many posts on here about growers leaving their plants to friends and families

then to return ....

and the plants totally screwed...

avoid and play catch up on your return

no food for 2 weeks is an easy fix for you

or face nute issues etc etc

imo

ps in most cases any preprepared nutes in tap water will break down

over the next 3-4 days, unless sterile and light protected, foilar feed is an easier option

Top dress and have him/her only water..

I left my plants to pops for a week and came back to them flooded and dying. He grows too... had to toss them.

Good luck to you, but even experienced growers can screw up plants they're not familiar with.
