Root rot 2 weeks before harvest

If this has been covered, I'm sorry..

My question;

I'm 16 days away from harvest.. I've discovered root rot. Is it wise to let them finish out or chop down?

Due to screen, I can't fully access the roots to clean the buckets out. This is also my first encounter with rot. I've been adding calcium hydrochlorite , but can't tell if it's helping. Especially sense I can't rinse the roots.

I'm sure it was due to the heat swings in my area. I just made a chiller week ago. Water was 70-76


I have photos and can take more if needed. Roots are light brown. Smells like a pond. Lite swirl film on surface..

Trics are still clear..

Strain- RP Skywalker

My system:
UDWC
22gal
5.9 ph
750-800 ppm
61-67 water
79 degree @ 45% temp
1000w hps
RO (6ppm) water

The plant on the right was runt to begin with and was the first to show signs. It's mostly wilted or buds are starting to turn yellow. The bigger on has just started to show signs of wilt.

Any input is appreciated.

To update,

Flushing the past few days with calcium hydrochlorite seems to be helping. Girls ate 100ppm from yesterday. They were barely taking up 10ppm.

I was able to peak inside the one bucket and seems the bottom portion of roots look white. But the base to 3 inches where the water level drops and rises is brown.

Using gloves, tried to scoop out particles. If you scrape the upper roots, you can see the brown come off and it's white underneath. Only a small set of roots gave away from pulling.

I'll be updating till harvest to help others with udwc/rdwc running a scrog. As I've read a lot of posts regarding rot but no info on what to do if you can't access the buckets.

Hopefully I can keep them alive and eating for 15 more days.

Also I'll update with photos and fix the ones in my first post.

Hopefully this gives some hope to those in similar situation.

why don't you raise the water level for 12 or 24 hrs and try to submerge most of the netpot?

Thanks for your time man.

My daily top off is 2-3 gal, which touches the bottom of the net pots when full. If I fill it more, water will leak from sides due to air stone hose.

gotcha.
how about pouring it down from the top of the netpot? that root rot is a bitch to get rid of.

Hmmm. I was wondering this. You sugesting straight up RO water or h202/ calcium hydrochlorite mixed with water, poured from top of net pot?

Being my first time with the rot, defiantly a buzz killer for it to happen at the most important part of the grow.

exactly. i'd flood the hell out of it. you could just use your normal res water if it already the cal chlorite in it.

think of it this way, your plants are using energy to rebuild roots when they could be producintg lovely flowers.

hygrozyme did wonders in aeronautic applications against root rot, It might help too!

2 weeks to go, I'd chop and move to a bubble cloner, although there really is not enough evidence here to suggest Root Rot,

as in most cases 'SMELL' is the key, the mold/fungi is highly contagious, and if in a dwc type grow, you may as well start again, but sterile everything first, tho you have selected
calcium hydrochlorite, common household bleach is just as good and cheaper use at 5-10%,
one can only advise this correctly with pics, and natural light on the roots, but if those roots are white ...thats only a good sign

Your gonna need to bleach the living shit out of your system after harvest to not get root rot again. Every inch of it. Replace hoses, air pump stones and lines. Take this seriously or that system might as well be in the trash.

Hey buddy,
I was under impression that is used for a live Rez?

Hey man ,
Yeah I'll post pics tomorrow and try to take one inside bucket. I know my grow light is giving the wrong hue to photos. But Its really only effecting my runt plant. My bigger one just started to show signs of deficiency/ root lock. But not drooping. I have other babies in pre veg right now. Would you still smoke 2 week early plant with clear trics , make edibles or trash em? Just trying to make the best of 2-3 months of grow.

Hey,

I'm actually doing all new buckets, piping, adjustable scrog and moving outside of 4x4 tent . So if another issue comes up, I can at least isolate and access inside totes easier.

enzeymes. you want enzymes. lots of enzymes.

HYGROZYME, PONDZYME, STRESSZYME, BARLEY MALT…..anything will do with active enzymes. That's what they're made for to degrade decomposing roots.

Sorry for the flash, but here's how the looked tonight. I've been slowly working away at the brown mass. the root still holds on tight, but some of the outer rot does slide off when scraped.

Thanks for your suggestion, i've been looking up these products and seems alot of mixed review for rdwc/udwc. Has this worked for you in the past?

if root rot is still there, i'd almost guarantee that it is causing pH drop.

try dutchmaster zone. sterile root zone is best IMO for dwc.

Hygrozyme will fix that problem in two days.

Thank you for reinforcing my statement.

No I have not had this exact problem. I run my plants in soil, and they get a weekly application of enzymes to avoid this from happening. This could also be a sign from not enough aeration getting to the roots making things go anaerobic.

I did have this happen to one of my plants in flower that was sitting in soil. Being in soil I had to take the root ball out chisel away the nastiness pack in new soil/compost and hit it with some enzymes. The plant was devastated, but I still got a harvest.

Exactly, the root ball inside the bucket is so dense it smothered the air puck ( p.o.s. ) . I cut the line and strung another air stone from the top of the bucket. I'm guessing its been clogged for 2 weeks, right when both plants really took off. Both plants are also clogging my 2 inch piping. No more 5 gal buckets, that's for sure.

My local doesn't carry. I'll have to surf the web and obtain some if its that good. When you say two days, is that drooping/ fading process stops or they start perking up and swelling? My only drawback to hygrozyme was reading it can gunk up the system? Thanks for your reply man.

That's what kept throwing me off. My heartier plant is still uptaking, with only slightly tan roots. Smaller one has the rot, has 4 stalks still looking ok, rest have dried up and faded. My PH has been stable to slowly rising vs going down..

Go to a a petco or pet smart, and get a little bottle of either pondzyme or stresszyme. This is the same enzymes used in hygrozyme.

DO NOT UNDERESTIMATE DILUTION RATES!

This is to treat ponds and huge aquariums. I would dilute into a cup of water. and then dilute that further into reservoir. I am sure if you research (type in pondzyme application rate cannabis into google) you will find tons of info. Hygrozyme, cannazyme, biozyme etc. etc. are pitched to the cannabis crowds so they have easy dilution rates but EXTREME prices. pondzyme for 15$ will last you the rest of your life.

EM-1 is another good product with enzymes. It Effective microorganisms, and they will eat rot off of anything……including oil spills on the beach.
GOODLUCK
