Slime buildup using orca & great white?

HEllo everyboy,

I'm on my first dwc grow and I'm in the 4th week of flower with 2 blue og and I must say that look lovely lol

I've been using orca & great white together with my standard 1part hydro bloom feed ionic bloom also using carboload for the bennies and have noticed a foam buildup in my 2 plant dwc planter this past week and want to know if it's good bacteria or its bad?

Here are a few snaps of the roots
Here are a few of the plants

There isn't a nasty smell in the res just some foam around the edges and some clear slime here and there?

I change the res every 7days but it's impossible to remove the plants from the system because there just isn't the room so I've just been emptying and refilling with fresh mutes and enoculating with more bennies.

And advice on matinance for not being able to remove the plants from the system but still keep the red as clean as possible would be great
And type of products I could use to keep dead roots from turning bad and infecting my res would be cool also as I don't run anything apart from....
Ionic bloom
Pk boost
Carboload
Orca
Graet white

Thanks guys & girls

Although I can't see any issues with the agitation happening, I'd definitely take a closer look when you drain the rez. If the plants don't show any signs of distress-continue on...

Hi , thus us my first dwc grow after going through the motions of soil/coco/perlite&coco = dwc and Im a over obsessed grower that watches every little thing lol

I don't want to loose my girls now so slclose the the end lol do I need to be using a emzyme product from time to time for dealing with dead roots in the bottom of the res?
Like a mentioned ' I'm not able to remove the plants from the 70litre oxypot xl planter so I'm just emptying and refilling the res with fresh nutrients every 7days but then started thinking about the dead stuff that's trapped in between the roots when I empty the res?

I do have a chiller set to 19c with a 2c drift, 800lph pump in my res conceded to my chiller with 55lpm of air going through 8 airstones so water temp and DO level should be ok

Slime in hydro is usually algae. Research what to use to stop it. Hydroguard might help.
