DTW Top feed - Mixing up to 2 weeks of nutrient solution, bad idea?

[LoGiK287]

Hey everyone,

I just finished putting together a drain to waste drip feed system for my flowering tent set on a timer to feed at 2x2 min intervals each day.

I have a 36 Gal Resevoir (Black Sterlite tub) which would supply enough water for approx. 2 weeks on that schedule.

Growing SCROG in Coco /w 3 gal smart pots using GH trio nutrients and Calmag.

I've just filled the res fully for the first time, and now I remember reading somewhere that pre-mixing nutrients into your water ahead of time isn't good.

Just want to get some input on whether my nutrient water will degrade/turn after a while? Is there specific nutrients designed for mixing large batches ahead of time?

Cheers!

It a bad idea to pre mix. All the nutreants will separate and leave you with lockout and a vary low oxygen count now if you keep the tub aerated with a pump and oxygen stone you should b good for not separating and it will stay oxygenated

Right on, grabbed a pump and airstone to add to the res. I was thinking about keeping in on the 12/12 timer i have my lights on, that should be enough aeration?

My air pumps run 24/7 it keeps the roots happy
