New Grower DWC, Led, First time grow (3x Think Different)

...looks bacterial, maybe fungal...? Farqual, post it up in the Live Help Thread, and we'll have DWC guru confirm what it is,.. but roots it ain't!
 
Like you said never on the internet anywhere have I seen that... I cant wait to hear what the seasoned vets have to say !
 
:dunno:never seen anything like that ?... is the affected area kept above or below the water ?:Sharing One:
 
Quick advice is fill water/nute level to touching or just above the net pot base & keep it topped up ,maybe change the res 1st too ,just to be safe ?.

Maybe try to clean the affected area with something like a spray bottle ,see if it washes off while you make a fresh res (be super gentle)

Keep a close eye & see if it goes away ,keep us posted :Sharing One:
 
H202? Quick fix? With a res change obviously
 
I will max rep the dude who can tell us exactly WTF that shite is bro !.

Cowboy has a good point ...are you running any kinda sterile agent ?.If not & the problem persists it may be an idea to try some ?:Sharing One:Shes a beast :goodluck:
 
OMG what could that be? It apeared over night... Mold?

My girlfriend says it feels grainy, and it doesnt smell! I keep my res. temps always between 18 and 21 °C

Looks like calcium deposits that you get with hard water ( just a guess but thats what it looks like to me ) Too much Calcium????
 
Thanks for you posts guys! Im not a fan of H2O2, it would kill both, the good and bad bacteria. Since the undesired "whatever" seems to outcompete the good ones, H2O2 would make the problem worse. Or i would have to run with H2O2 for the rest of the grow.
Its a shame that you can't get Hydroguard/Aquashield in Europe, what sterile agent would you propose?
Don't like sterilizing a res either & much prefer bennie tea .Great white myco & molasses brewed for 48hrs works well :Cool bud:
 
Nice tipp! Does this reall work in DWC? I heard these microorganisms have problems to colonize the roots without a fitting subtrate like a "Biofiltre".

well, just my opinion but, your plants and roots look healthy, so I'd say don't mess with it. keep your ph in range and maybe get a water filter to reduce the ec of your water. I learned my lesson, I won't run tap water in hydro!
