I've never seen this......blisters (Pics)

[TGR]

Hello everyone. I have likely crossed paths with some of you at a previously enormous, but now defunct website/forum of similar orientation. I am stumped at a particular issue this has plagued an associate for some time. Please find photos attached of healthy (1(4)) [photo 5] and affected (remaining photos) plants. I have had several close but eventual misdiagnosis, and I would like to find the answer. These particular examples were in 55-60%RH, 1200ppm Botanicare Pro Bloom, 5 weeks, 1500ppm CO2 and 72-82°f

All my best, and thanks in advance,
TGR

Never saw anything like it....I am thinkig it is some kind of fungus or mold

Yeah, that was what I was thinking as well. Although, last time it came about at a much lower humidity, too. IDK, it does seem to have an overall effect though, so it would be nice to address it, somehow.

Also, it doesn't become apparent until bloom.

I had something like that... Went to the Heath Department and they cleared it right up for me lol.

looks like citrus scale fungus. what part of the world you in? are you near any citrus trees? i get shit that looks like that on my lime tree in the summer but it dies off in the winter. does it seem to affect your plant's growth? can you take another picture with some white light in there, so i can see it's color (citrus scale is cream colored and looks a little like the crusty buildup you get on a shower head with hard water). if it's not hurting the plants, fuck it. if it is robbing you of vigour, try a fungicide for fruit trees BEFORE you begin flowering next time. I prefer the metal based (copper and silver) fungicides because they are not terribly toxic to anything thats not a fungus, and the plants dont take up the metal unless you way overdo it.

last time? until bloom?

how many times has this cycled? i'm guessing you clean your grow area after each flower cycle?

 

[Coho]

Is it soft and squishes? Some mildews can do that. Is it white?

plant herpes this happens when u have a whore seriously jk ive never seen that shit looks crazy man.

Hey Dr Kynes, this was in mid SC area, I don't think there is citrus around, but I could be wrong. I will try the fungicide next time as it does seem to have some effect on vigor in the more heavily affected individuals. I will try and get another pic with proper light. Can you recommend a specific fungicide to try? Thanks

A couple time with varying degrees of impact. Yeah, it get's cleaned out very well and there are no signs during veg.

No, it looks like it would be but it is rather rigid. It seems it is the plant itself reacting to something and causing these, pustules? I would say it has to be a fungus, but didn't know how to address it or positively identify it.

plant herpes

Gah, that will NEVER go away.. haha

Perhaps it is just some sort of stress to the stems and they are trying to insulate or strengthen..it doesn't look foreign to the plant...it looks like growth coming out of the stems...Hell I have no idea what it could be...but if the plants themselves look good then I would document this growth, but probably not try too hard to fix it...

i found this sounds about right http://en.wikipedia.org/wiki/Erwinia_chrysanthemi

 

[missnu]

Now the first pic with all the white bumps around the base of the stem, that is normal..the part of the stem closest to the dirt once you are flowering starts to turn positively barklike...and it looks like your plant just overdid it, because the first pic looks like the base of all my plants...but the other pics where it shows large nodules of this crust it looks irregular to say the least, anyway the stem nearest the soil sometimes gets confused and will start to try to grow roots above the soil so you will get these little bumps...

the 5th pic looks normal too..so only a few shots and angles look out of the normal scope, but it doesn't look like a problem to me, but as I said I have no idea...so really...I have no idea.

• Lichens are actually two organisms in one body. They are a combination of a specialized fungus and a specialized type of algae in a symbiotic relationship. Lichens appear as colonies of white or other colored, flaky material over dead or dying tree limbs, especially during the winter months or on branches not receiving sunlight. They are not particular about what kind of trees they attach and may be found on various fruit trees, like apple trees or pear trees.
  
  

Symbiosis

• Fungi cannot produce their own food and must derive nutrients from other organisms. This is known as parasitism. In lichens, the specialized fungi bond with algae, which are capable of photosynthesizing sunlight into energy, which is then shared with the host fungus. Lichens may also use a special type of bacteria known as cyanobacteria instead of algae

I would wash your stalks with high ph'd water

Here are some more photos. Coincidentally, I thought I was also treating a MG deficiency, and the leaves detailed I realize could be a symptom of this condition as well. All the leaves aren't like this, and the most heavily affected plants aren't displaying this leaf condition.

Yeah, I'm not extremely worried, but if I can fine tune I would really like to get rid of any anomalies before they manifest themselves into something else. It wasn't there before. It has been around for a little bit but I just don't want it to suddenly get out of control, you know?

Well, the biggest difference from that description, I think, is that these are very rigid, not soft. They appear to be fluffy and pillow like but are actually very tough. Also, there is no blackening of the leaves.

Can't hurt, I'll give that a try. By high you mean high 7's or..?

Thanks again, everyone, for your input!

i've heard of the plant producing sap that would harden this may be what is on the main stem and branches

 

[TriPurple]

I've seen this before (the hard white stuff) never caused any problems.

Quite possibly, I do notice it around the sites where trimming has been performed to make it fit the screen properly. Still, it seems that I wouldn't hurt to maybe try a fungicide next time, just to see what happens?

I prefer the metal based (copper and silver) fungicides because they are not terribly toxic to anything thats not a fungus

Maybe something like "Liquid Copper"? Also, I see others like "Eco-smart" (completely non toxic), have you found these to not be effective?

it looks like the stems are becoming woody. What is the breakdown of ur PPM? Ie water starting? What is the breakdown of the N P K ? I think the woodyness is a def of P or K but not sure which.

The nutes are at 1200ppm of the one part Botanicare Pure Blend Pro (2.5-3-5) and I let it drift between 1200 and 900, to allow for different levels of uptake. It's been the same nutes for a long, long time but have never really seen anything like this until relatively recently.

It's basically a flood/drain slab gutter system, and waters about 4-5 times a day. Anything less or more seems to either over soak or dry out too much.
