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!

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?

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
