How long can I store mixed lucas formula?

Can a mixed batch of lucas formula (flora micro and flora bloom) last a week if its stored in a cool and dark place with the cap on? or should it be tossed ? also, will the ph of the mix stay the same throughout the week if its kept in said place?

Thanks!

You should never premix your nutrients.

I'm interested in this as well. Just bought a gallon of RO for my plants in early veg. Premixed a gallons worth of GH Flora nutes and have an air stone in there. I was hoping this would last about 2 weeks watering small soil pots. That is unless the nute solution decays over time?

Don't premix your nutes, mix them as you need them.

In the past, I would mix up a gallon of GH MaxiGro/Bloom which would be enough for a week

I found it would develop a non-pleasant odour, but seemed to work without issues....I think the pH will drift but I never re-tested

It worked best storing in glass mason jars with lids on and store in a dark/cool place

I now typically only mix for one feeding at a time...and just toss any extras
