4 days old water with nutes - can I use it?

[Helmut79]

4 days old water have had indirect contact with light.

I really don't want to trow away nutes in this water, but the thing is that something has started to grow there already. Probably brown algae.

How bad could it be for the plants, if I water once with this?

There's one factor to keep in mind - roots aren't fully developed yet, so they're kind of soaked up.

Could there be some kind of danger of root slime? What about bad bacteria?

It's still coco.

yeah keeping water and nutes in some container for that long and your getting a funky smell. you will fuck up that grow .. you need to aerate and keep cooler than 70 deg. if you cant then dump that shit and re do your set up to just use it all up. at each watering
and give fresh PHed water/ nutes. with a lil run off .. that will give it a good flushing and fresh nutes. if you continue to try and save the water and use it . on your plants they will hate it . think it as if you leave your milk out for a few days . then try to drink it... to save a buck . .. shit ill eat ramen. and give my plants the best nutes. cuz in the end your yields will get you a gram a watt. , and not the .25 gram a watt. you will get cutting corners, if not killing your girls. . imo.

I'm not lazy. I want to know. Tried really hard to find some info, but couldn't.

Everything is about DWC aquariums - brown algae is bad.

What about Coco? They are 2 different kind of growing medium.

I'd be glad to know the answer.

Thank you for your reply. It sums it up pretty well I guess.
