I think it is root rot...

do you have airstones in each bucket, because i think it is lack of oxygen to the root area...what i see is...light brown roots, rotted off...It the bottom of that stalk darkening?

nitrozyme is the enzyme product you have on hand...cool
so that fills in for hygrozyme...for the time being.
floralicious...is similar to what to Liquid Karma, B-52, and other catalyst vit-b products...So that's cool.

with floralicious...and I will double check to make sure I am not stearing you wrong...I ck'd...I was right

I would use this mix...
per gallon.
0 grow
5ml micro
10ml bloom
10ml floralicious
mix nitrozyme according to directions...this should be well within ppm limits for the size plants you have.

both the floralicious and nitrozyme will keep your rez healthy unless you create a atmospheric problem.

the airstones are the key.


I think the one plant is fried...I think the top will follow and the sooner you make the decision to pull the plug...the sooner you stop wasting time and space on the ol girl...pitty...

since you recirculate...this is something that can spread maybe?...there is also a brown algae, I believe...

the 2nd pick...looks OK, like the water was real low and the roots near the netpot dried up at one point.

Now you have a couple options between me and snoop...

I have a couple plans for you to consider once I get answers to q's at top
