What’s going on here?

[Salton]

I have a rdwc system and on my first grow with it.
This has come up overnight, and moving fast so I hope someone can help.
I’m using Aqua flakes nutes, keeping the PH 5.5-6.0 for the most part, but ph was 6.2 this morning.
There is a variety of strains.
I keep the Rez water at 69 degrees and the temps have been in the 72-81 range, but I introduced CO2 and raised the temps to mid 80s this week during light on and back to low 70s in dark.

I could be wrong....so I'm sure others will chime in here.

Just my opinion.

Thank you for your input. I have a hunch I’m going to check out. If I’m right I could be in trouble.

So my son took out a couple of plants that were underperforming. I didn’t think about the roots sitting in the buckets rotting. So it would seem that’s the issue.
I drained last night and added only RO Water and SLF-100.
I will drain again tonight and refill.
Hopefully I can stop this.
Learning the hard way is my only path.

Hope you get it figured out....you are a long way in to have major problems......

Most people run some kind of anti-pythium additives like z7 or the like. You may want to check into those.

People like @Rider509 @Bowl Nugz n' harmony @Grandpa Tokin all know way more about RDWC and DWC than myself...

I’m using SLF-100 it’s a similar product.
It seems to work well, but leaving two rotting root balls in the buckets was asking for problems.
This is my first hydro grow and I have learned a lot about what not to do.
I hope I have not ruined this grow.
I think I’ll be ok.
It looked really good until this fiasco.

Hydro tends to bounce back pretty fast....

I didn't know SLF-100 was similar....just learned something....

I think you will be fine....you caught it in time to have a decent harvest...

Thanks for the good thoughts. I hope you are right.
