Clear substance on leaves.

[Linux50]

hi everyone,

Has anyone seen this before on their leaves? It a substance on a leaf...

 

[Javadog]

Wow, but I'd like a better look at that one.

I want to ask if you've sneezed recently, but only in humor...

There are fungi that look like goo, but I do not think that that
is one of those. (Witches Butter)

It is more likely the effect of leaves laying on each other....respiration.

Good luck,

JD

Indoors or out .....is the clear stuff sticky ?

If it's outdoor and your growing your plants anywhere near a large tree above it could be sap dropping from a tree into your plants .....indoor I have no clue what It could be besides semen JK ......is it in or out

Looks like vapor pressure deficit. Look it up on line you'll get a better explanation than i could give you.

Ive seen this before and it has destroyed some of my babies, have no clue but if i were to guess it would be some type of fungus. I would remove that leaf asap without trying to spread it.

Godbless you. Wait you didn't sneeze?

Mmm witches butter.
Usually named for the yellow "troll-cat" vomit appearance. A type of slime mold that usually feeds on other microbeasties. I had it twice in a month in my backyard. Amazing how it moves in a days time.

Honey mushroom on the other hand can be a parasitic fungi, wide array of color. But usually eats hard wood/bark/old park benches.

That looks like early stage gummosis we in the south east get on fruiting/citrus plants. If the spot turns rust color and or the stem to the leaf splits and oozes..

@KryptoBud said "vpd" but a cup'o'joe worth of Google and I can't find anything resembling your snot-like exude in descriptions or images. Maybe someone knowledgeable on brix can chime in on if high sugar level can make it look like that. I do remember some sappy looking trimming pix before.

Why does this stuff interest me? If you trim it off, can you put in a ziplock bag and take a photo of it 24hrs later?

Edit:

Froghopper?

So a spittlebug has a different name.. Interesting.

@Linux50 First video, ~58seconds in.

So it's like a form of barotrauma. I learned something new today. Thanks!

Vapor Pressure Deficit is the relationship between the temperature and relative humidity. Having them in the proper ranges can make or break a grow.
orange is optimal white is o.k blues are detrimental.
What any of this has to do with how the semen got on your plant is still a mystery.

 

[Javadog]

I have a slew of humidifiers, of all sorts, from my mushroom
fruiting chambers, but what I am not going to do is to put one
into my tent.....not without a hygrotherm or some such.

What sort of passive techniques might one use, I wonder?

That's not what vpd is. It's the difference in the vapor pressure of the air and the pressure inside the leaf.

high humidity=low pressure low humidity=high pressure

What can cause water droplets to form on leaves is having low enough pressure that the plant can't transpire due to saturated air. This causes pressure inside the plant to rise. If the soil is wet it creates pressure on the roots forcing water from the leaves. It's called
guttation (sp?)


The op didn't post any info so it's all speculation anyway. What do you think could have caused it?

...Semen...
Condensation due to improper VPD and poor air circulation... but my money is on the Semen.

I went with mucus from the get-go. :0)

You're probably right
