Root rot day 25 flower, options? Help please.

A few days ago I noticed dark spot on a few of the roots coming out the netpot on one of my plants, i've had it happen before from putting the water level too high and figured that was it because on the last res change I filled it up to encourage more roots to come out. And there were new roots coming out and I heard on the tea thread once new roots come out its a good sign.

Well today those roots were broken off from where they were brown. How do I go about removing those strands that rotted out? Its all intertwined with the good roots i've tried moving the roots around while they were submerged in water but I didn't want to be too rough and ruin my good roots.

If I used aquashield would that compost the dead roots?

Not sure how this happened, res is 64-66F and Ive had a bunch of successful runs at that water temp. I did add another air stone to all my buckets as they were only getting 6.66LPM of air so now they are doubled at 13.33.

Overall plants appear to be healthy, nice fat buds forming for only day 25 of flower. Leaves look healthy pointing upwards not drooping or anything. Drinking half gallon a day. Feed is around 1.2EC and PH drifts from 5.6-6.0.

Shitty timing as hydro store is closed for the holidays, but once they open I will get some castings and aquashield and a myco product and brew some tea.

So the ultimate question, how badly will this affect my yields? There is still a good amount of roots in the water that are white and strong and not mushing together, but the bits that were mushed have detached.
 
Because of the good water temp, I would have to guess that the cause was either low DO due to the lower LPM which gave bacteria an open window, or if perhaps your luck just ran out as you almost always have nasties that cause pythium in your water, even though you minimize your chances through low water temp and such. Anywho, Hydroguard (the new form of Aquashield, same price), and it's bacteria dissolve dead plant material and break them down into food for your plants and beneficials. I never removed broken roots themselves, however if you empty your buckets, fill them as full as possible with fresh plain water, then completely drain again and most if not all dead root material should be left on the bottom or side of your bucket for you too just pick out. I personally have used Hydroguard/Aquashield to cure pythium and prevent it, so I believe your best option would be too either buy it and apply it asap and improve your LPM if possible, but that doesn't sound like your cause of the pythium or brew compost tea, Hydroguard is likely the route I'd go but the tea would work well too...I think everyone has odds of getting it no matter what. But since the use of Hydroguard, I haven't had the slightest worry, the infected brown roots will stay brown after the Hydroguard, but you'll see an explosion of pearly white roots out of the old ones. Some people even trim off dead/infected roots...because I'm using Hydroguard, I personally just leave them be and get any dead material at the bottom of my buckets between res changes.

P.S. * EDIT * You can try H202, and may have success, but look up the definition of the word "sterile" and then tell me how well you'd like your root zone sterilized...over colonizing bennies is IMHO much more doable and realistic then killing everything but your roots in your root zone! Just my .02 though, I had a nasty run with pythium and H202 proved nearly useless if not re-applied every 24 hours, and even at that, the results of Hydroguard were far more impressive. If not at least controlled, I'm not sure you'd have one. However, if you take action fast, your plants will recover in no time. Cannabis is a tough plant, and if properly treated, can handle nearly anything. If treated soon, your yield IMO will be the same just might take a few extra days of flower. Happy Growing, and good luck!

I got some Hydroguard last night and put some in 2ml/gal like the label says.

Doesn't look like its moving onto the healthy roots.

Plant still looks amazing, hope it pulls thru. Was a mild case of rot. Can rot only affect a couple roots and leave the rest alone? All pictures I see online of rot the whole root mass is affected.

Hydroguard won't 'cure' the infected roots, they will stay brown. It's a bacteria that basically out competes the bad bacteria allowing your plant to grow healthy and normally. It will aid in new root growth, and you should have some pearly white roots start growing any time.
 
Thanks -- I don't have any hope for those roots, just trying to break them down since they are tangled up with the good roots.

I already have pearly whites coming out, but I hear this makes more so i'm looking forward to that aspect of the product as well.
 
Just added more Hydroguard today. Roots still look bad.

Not sure what im dealing with, the res doesnt smell or anything and the roots aren't slimy nor do they have gunk on them. They are just turning brown and falling apart.

Seems to be progressing onto the healthy roots now. The unaffected roots are thick and will take a while to break down like the thin ones, but im worried.

Shes looking so good i'd hate to chop her down and can her. About 30 days left of flower.

Tough call man. You might have too much pythium in there, I'm no expert though. I was experiencing a similar issue in a couple of my solo buckets so I put in some H2O2 to kill everything. I did that twice over 5 days and I got white roots again. H2O2 dissolves/evaporates within about 24 hrs, so I added hydroguard after a couple days from the last treatment. My theory is I've killed everything and am now introducing bacillus bacteria (hydroguard) and hopefully it will be able to out compete any new signs of pythium. I do not have this problem in my rdwc system and I'm guessing it's because that is running through a chiller at 65 deg and these buckets are closer to 74-76.

Infected brown roots will NEVER recover, perhaps not be as dark brown or smell bad, but will stay brown. Look at the end of those roots for white growth and there ya go. Which it sounds like you're looking for all the right things. And it's possible root rot could take affect, damage some roots, then something like lower temps snuff it out or keep it from growing. But generally if it's there and alive then it's growing and spreading.
*EDIT* Forgot to mention, 2ml is the same strength I do. First you'll notice a halt in the spread of it, then a well needed resumption of root growth/

I'm going to bring the plant into the shower tonight and spray the root mass vigorously. There are new white roots coming out the bottom of the netpot that appear healthy, white and fuzzy and strong, a little tug and they stay intact.

Nothing smells though, plant is perky still. Wouldn't guess by looking at it its going under root issues. Packing on a lot of weight going into week 4.

I did notice my ppm rise from a level that the plant previously liked.
 
Hope your roots make it!

I had a bad case of root aphids once. There was a gap near the root zone and my container. I used zone, orca, h202, etc. Not at the same time though. Would do couple day intervals. Not sure if that helps. Still ended with an okay yield but if I was doing 12 oz as normal for the strain, I only got 8 of good looking bud. Hash pile looked great though, lol.
 
Im hoping it will pull thru. Only 4 weeks left of flower.

It's already cloned so I won't lose the genetics, i'm hoping to pull 4 oz given the issues i've been having. I could never do 12oz off a plant, thats ridiculous.

I'm just not that good or haven't found a strain that can do that. This is my first time doing a perpetual so maybe i'll learn the strain enough to improve those numbers.
 
It's all about that root zone conditioner (expensive dutchmaster product; h202). Thats my shit right there.... And cal-mag. 2 must-haves~
 
I never claimed it did. I just said it was my shit. Meaning I think its one of the most important nute(s). The h202/root zone conditioner is for root rot.

Close,but wrong...
The bacteria eat the bad bacteria causing the root-rot..ENZYMES eat the roots/organic matter.
Get some panty hose and "sock" your water pump,it will filter out debris for cleaning,get some stress zyme if you're NOT gonna clean,add it to it res,and start brewing tea in the mean time.
Www.fungiperfecti.com for myco.6bucks,one ounce,shames the competition.
Roots excellurator if you're rolling in the dough...add 5gallons of water to a bucket,some molasses,and an air stone,and a tablespoon of Myco-grow,come back 36hrs later,strain,add a few cups to ur res,pat Yourself on the back.

Why use a product,then use a product that negates that product? Makes no sense to me...
