Second grow and trying to figure out what's in the rez. Didnt encounter this on first grow. What would gff look like of it wasn't alive in rez? There is like little pieces almost like coffee grounds in rez. Any ideas

No experience with bennies, I run near sterile. What medium? Water source? Is gff a powder? I'm on my 9th or 10th run DWC the only thing I've had that looked like coffee grounds was when some coir dropped through the net pot.

Its in a rapid rooter in a net pot with hydroton. I use tap water filtered tap water about 80ppm. The gff is liquid. Its like something isn't dissolved but I don't use anything that should do that wondering if the bennies just ain't alive or something

Its either hydroton if you didn't wash well enough
Or "fall-out" of nutrient solution.
This naturally can happen alittle, but can be cause by mixing concentrates, not stirring well enough between adding different nutes, or adding them in the wrong order.

Can you strain some of it out? Visual aids are big help. I wouldn't think that, if the bennies died, they would collect into little grains... but again no experience. @Destroyer of chairs almost lost his girls because of hydroguard in DWC. He went coir and his girls recovered beautifully.

I washed hydroton pretty well I think I usually over do stuff. I use gh trio and always go calmag then micro then grow then bloom i stir after adding each plus let the air stone help mix b4 adding next one then ph then bennies last. The only difference between this grow and last is its winter now so water is colder.

I would rather say I almost lost my ladies cause of piss poor performance on my part, neglecting their needs cause I were overwhelmed :D at the very least blame dwc not hydroguard which I'm pretty sure made them hang on long enough for me to transplant to coir :'D

Don't think that "grain" is bennies though. Money on hydroton or fall out from solution.

Bennies saved my 3 girls on last grow. So this fall out thing is something I'm gonna have to research. I'm only doing one plant this time

So far I'm reading that any sediment from particulate in nutes should be inert and not hurt and could be from water temp fluctuations. I usually use cool water from tap but it gets colder as time goes on so wonder if thats it. Plant seems fine roots are growing like crazy

Oh yeah, the particulate shouldn't hurt anything.
As long as it doesn't become excessive

I re rinsed the hydroton and caught all the rinse water in a bucket it was crystal clear maybe its alge im doing rez change this evening and not gonna use the gff since the water is cold right now and see if it happens again. Probably uses some h202 to clean everything
