Questions [Completed] Is this girl ok?

That’s a good job. I’d leave it alone and assess what you end up with in the end. If you end up with a lot of larf, take more next time. A lot depends on environment and light

Hello and sorry you’re having a problem 😢

so I’m not sure on this one as there are many things going on here

did this just all of the sudden come about? Were there times of really high humidity with no real air flow?

almost looks like bud rot but I don’t think that’s it. What’s odd is that it is lower stuff and it looks like the plant is a bit choked in that area for air flow.

it could be that the plant just isn’t getting enough air flow through it

i would maybe try to trim up/Lolly pop the plant from the bottom clearing out the bad stuff and opening the inside of the plant to let it breath

so I see you say it is 10 weeks old but when did you flip it to flower?

and are you saying you’re giving it 4L per day? Maybe she is getting overwatered 🤔

Canna A, B and Cal Mag at about 3mil per litre currently

This sounds high to me, but I don’t use Canna. Over feeding can cause pistils to darken prematurely.  Are your EC in and out balanced? If they are, no worries

There are little white wrigglers at the top of the cocoa when I water

definitely sounds like springtails. I get them by the cup full. They are actually beneficial and eat dead and decaying organic material, pooping out fertilizer. Your problem most likely isn’t related to this. I wouldn’t waste energy fighting springtails

Oh, one more thing, I did have these in a scrog net and had to remove it to get the other plants out.  There is a good chance I damaged these when trying to disentangle the netting.

Yes, you can severely bruise the tender white pistils by brushing against them. Ideally you don’t want to touch or brush against them if you can avoid it. This is a real possibility as there are a few pistils that don’t look dark, but not many

The upper canopy looks a bit dense. That can definitely be a cause of mold forming. If it were my grow, I’d thin that canopy and push more air through it. An oscillating fan is your best friend to fight bud rot.

Hopefully something here helps identify the issue

Thanks for the tips John and Monkey.

@JohnCarlson,

Humidity - yes the humidity went off the scale in the tent for a week or more - that's when my other girls developed severe bud rot. 

Flipping to flower - They are autos, so no flipping, they just went into flower, one is a week or so behind the other. 

4L water - I thought about overwatering too, but I am only getting about 10% to 15% run off in cocoa, so I think it ok.

@MonkeyDo,

EC in and out is generally ok.  I get occasional spikes in the output, maybe from 1.5ish to 2.5 in one feed. 

Damage - I think this is the most likely cause to be fair, I am going to remove the lower small buds that have turned brown and try to open the canopy out a bit.

Fan - I have a decent 8inch oscillating desk fan in there going all the time, so think there should be enough air flow.  It's directed  below the canopy.  Maybe I should direct it into the canopy, but I've heard varying ideas about doing that.

Cheers

From mid flower till harvest, I try to have air actively pushing through the buds to avoid rot setting in. Stagnant air is a nursery for bud rot. I run at least 3 fans in my tents. One low on or near the floor, one oscillating through the canopy, and one mixing the air at the top of the tent. To avoid bruising the tender white pistils make sure to use some kind of oscillation in the canopy area so as to not dry them out prematurely. If the air through the buds isn’t blowing constantly in one place the plant usually is fine.

Yeah I'm guessing the humidity is what caused it and I know you said you have a fan, but I don't think it was enough for the high humidity.

I'm not sure what strain you are running, what is the normal "weeks" or "days" this should finish? Might have got set back with all the humidity. I've run some autos out to 90 days.

I get you are getting that runoff, but in my opinion, I like to let mine dry out to half dry at least, and some of my plants love to get super dry. Not sure what size pots you're using, but in my experience, say a 5 gal pot, the plants wouldn't be drinking that much every day unless they were in full rip with larger buds growing.

When I've seen "bumping" or "touching" the buds and it causing them to darken, it never looked like this, this looks more like "dead", the whole bud spot, so I'm leaning more to bud rot.

lollipop and trim her up and push through brother, it will come around 😎 Keep up the great work!

I have to disagree. The media is Coco and coco works best when kept wet constantly. You cannot overwater properly prepared coco. For soil runs I do let the moisture cycle high and low, but not coco

@MonkeyDo, yes my understanding from everything I've read and heard here about coco, is that it is almost impossible to overwater. As Monkey says, just mustn't dry out.

I've trimmed her quite a lot already, not really done the lollipop thing, but looked it up and I think it looks ok at the moment. 

I checked a load of the little brown buds and there is no sign of anything other than brown colour. No hair or bugs or growth, so I think they should be ok for edibles.

Just got to clear up all the trim and get it decarboxylated for some edibles before the missus gets home.

I'll add a photo later, maybe tomorrow.

Having looked up how to lollipop and realising that it's a bit late, I've done what I can and just hope they come to something in the end.

Here are the before and after photos, now just wait to see how they get on.

What do you think guys, should I leave it at that for now?

I've also reduced the nutrient mix down to 1 mil per 1 litre each of Canna A/B and CalMag.  Still using 4 litres into each plant and will monitor as this may reduce due to the reduction in the growth.

Again, many thanks for the hints and tips on this.

Cheers
