Canna CoCo A+B : How long can a batch of mixed nutes last...

Im using the full line of Canna Coco products. A+B, Pk 13/14, CannaBoost, Rhizotonic, CannaZyme... and CaliMagic..
Im using Sunshine #4 Mix in 7 gal SmartPots...
I feed pretty much once / day, sometimes 2x late flowering...

I have a 30 Gal bucket i like to mix up big batches in and i was wondering how long it is ok to let the mixed nutes just sit in the bucket rez...
this is the bucket, it is air tight : http://www.amazon.com/gp/product/B0025QI4XC/ref=oh_details_o08_s02_i00?ie=UTF8&psc=1
course after reading on my own i have seen threads with people saying 3 days to 3 weeks ;p

oh and is it a good idea to put airstones in the nute rez?

any suggestions?

I personally hand water my coco using the entire CANNA coco line except the Boost actually. I use my water up in 4 days tops otherwise shit starts to precipitate out of solution.
Do you use the Boost? I think i need to but it's fairly expensive to me so i've just been using other supplements.

i have been using the 1/2 str boost/molasses combo... i dunno i dont really have enough data to say one way or the other.
i am a long time DWC grower who is just finishing (@45 days flower atm) my 1st coco grow.
the buyers at the various dispensaries around here all recommend sunshine#4 w/ full canna line, so who am i to say /shrug

i never let my DWC rez go over a week due to nute imbalances, but i figure with this type of system that isnt an issue.

can you explain what to look for that would show its gone bad, ive got a bucket im just leaving alone to see how long i can let it sit there before it goes bad.

After day 4 from fresh mixed nutes, I won't use the last little bit in the buck. I'll go to the sink and dump it out and that's when i started to notice this thin film building up on the bottom and along the water line. There was a rough ring around each height the water sat at between watering. My plants in veg seem do do great even when i was in a huge hurry a few times and didn't have fresh nutes mixed up...so i watered with the last bits in the bucket...showed nothing negative. It's just when i throw them into flower i feel they possibly get Micro and N hungry...i'm curious if i should shift my pH a bit but my pH is going to flux a little bit anyways.

hope this helps a bit man, and good luck with you coco!

well... i went to 3 weeks with no problems, though i do have a rather large air pump running 24x7...
if that helps anyone.

I read this over a few times and what I'm trying to figure out is why you keep calling this a coco grow when you are using peat with coco nutes.

Anything is fine as long as you maintain the ph. For many people, myself included, canna's ph goes crazy high when airated. I have let a solution sit for a few days but no more if using rhizo. I stopped using a res altogether and hand water now.

Forgot to mention that a circulation pump worked pretty well instead of a air stone for me. Could easily let something sit a week even in my little 8 gal res.

I've never used a res, i went from soil to coir and just kept hand watering, setting up a res and drip system just seemed like a hassle.

I did a hand watering last grow, I get out too much for that, I hated being a slave to the room, 2 days does not a weekend make ( I work 4-10's ). This time, I can go 6 days without intervention if needed.
More fishing time at the lake/beach for sure this grow. A simple res and pump setup is not much to do for such freedom.

Peace and Great Grows
