leaves r collecting water, like sweating

k heres the dealio i underlined the problem incase you dont wana read a lot

theyre 4 bushy unsexed plants started from seed, in individual net pots in rockwool cubes w hydroton, all in a single 5 gal bucket w a airstone and water sprayer, theyre about 2 weeks old and have been doin totally normal and healthy and fine up until now. theyre under a 2 ft 2 bulb t5 with veg bulbs in it, in front on them is a 4 ft t12 with veg bulbs and behind them is a 2 ft t8 with flowering bulbs. theyve only been on 24 hrs light and the plants are rotated all the time.

a few of the better sized leaves have started to make clear liquid on them in the center of the leaf. its not sticky or anything its just like water, they dont get sprayed or foliar fed or anything its just like theyre sweating

has anybody ever had this happen or know what could be causin it n is it bad?

thanks in advance

Could it just be humidity?
Do you have water collecting on any walls?

no water collecting anywhere else as far as i can tell. they had a fan blowing directly on them for a while but it was recently taken off. im thinking thats the problem but i duno.
i googled a bunch of crap too, like cannabis leaves perspiring and stuff like that but i couldnt find any information about water just like coming out of the leaves

this happens to my leaves about 5 or 6 of the leaves each grow. i never really bothered about it, doesnt affect yield, but i wouldnt mind knowing what it is

I have this happen on an aerogarden that I grow lettuce in but lettuce already has a high water content. Add aero and it gets really wet leaves.
Idk if there could be any relevance though.
good luck

i get that too i havnt seen anything bad from it i usually try and wipe it off with a soft clean cloth i havnt got it on the bud just a few leaves here and there its just like your lawn in the morning that have dew drops thats it

Don't worry about it, it wont get any worse trust me... It happens to about 3-4 leaves each grow, its just the plants coming in contact with one another... Don't stress

that should be the leaves sweating on eachother. when one leaf is sitting on top of another (touching) under the light, it causes it to sweat you can say. i dont know how it will effect the harvest really, because you are under 24 hour light for now. when you switch over to 12/12 light, when lights are off and it starts to cool in the room, the sweats and water on the leaves dry and some turn into powder mildew.

sweet thanks for the replies, just started 12/12 the other day so hopefuly everything goes good now.
thanks again
peace

pretty old thread I know, but just did a bit of research on this subject as it just happen to my plants under my new LED fixture, was wondering why and what it was a sign of

just a copy/past from another forum:

What your plants are doing is called transpiration and it is a part of photosynthesis. As your plants roots take in H2O (water) during photolysis (the light period), the thylakoids of the grana in the chloroplasts of the leaves breakdown most of the H2Omolecules into H+ and O-- ions, the O-- ions automatically form covalent bonds and make O2 (oxygen) which exits the plant through the stomata (stomas) located on the lower epidermal layer (underside) of the leaves. Some of the H2O is not split up and exits the plant through the stomata as H2O vapor. During the carbon dioxide fixation period (the dark period; however, carbon dioxide fixation occurs during the day as well) CO2 that has been absorbed through the stomata is broken up in the stroma of the grana in the chloroplasts of the leaves. They bond with the H+ ions left over from photolysis and form C6H12O6 (glucose) which is converted into starches and transported to the meristematic tissues (grow points, tips of roots and shoots). The reason that plants transpire is to both cool the lower parts of the canopy and raise the humidity near the stomata which accelerates photosynthesis. The water you are noticing is just a buildup of the water vapor that has exited your leaves.
The rate of which your plant photosynthesizes is determined by the amount of which the stomata are open or closed which is determined by the Turgur pressure (H2O pressure) within the plant. Humidity, amount of light, temperature, and CO2 concentration are the main factors that determine turgur pressure. In no light, the stomata completely close, also in temperatures above 100F or below 30F will also completely close stomata, low humidity (below 20% RH) will cause closing of stomata, CO2 concentration too high (above 2000 ppm) will also close stomata.
By the sound of things, your plants stomata are wide open and with 24/7 light, they are maximizing their potential for photosynthesis to occur. Keep those climates just how they are and those will be some happy plants.
Let me know if you have any questions.

Dunno how old this thread is, just found it through Google.

Exactly what Slipon said ^^

Heres a couple pics of mine this morning..

Using Samsung s2 sorry I cant enlarge the pics..

Get the fan back on them, having setting water could cause mold.

They look to me as if they are over watered in the first place. The fan should help evaporate the condensation. I get that but it's usually where two leaves overlap and touch each other.

Then trim them.

I used to get condensation form on my lights/wing at lights on..which then dripped onto girls as the bulb heated up...
