how long can i run organic nutes in my hydro

[chaoticbliss36]

i have hydro farm recirculating buckets filled with coco and with a drip ring on top... i am using an organic line with a lot of products(Humboldt nutrients) and i was wondering how long some of you other organic growers allowed yours to run...
i have been changing it every 4-5 days but i am almost out of nutes and almost done so i was hoping i could stretch it.


thanks

Most resources online mention using it for 2 weeks. Can't imagine why you would replace every 4-5 days.

I do it for a month. Worst case some nutrient gets deficient and growth slows down.
