Not sure whats going on , its 10 days after sprouting, first picture is the best i can do,i planted 2 seeds here are pictures of both, i am using happy frog and light are about 30 inches

Looks like the soil is too wet and you should not get the leaves wet the light can burn the leaves acting like a magnifying glass through the droplets

Advise against spraying a plant, ever, unless it becomes absolutely necessary to treat bugs or mold.
Best to let that soil dry completely out before watering again, then maintain these wet dry cycles throughout the plant’s life. It is necessary for good root health.

I’d say either the soil is too wet or your humidity levels (vpd) could be off, I killed 3 seedlings by overwatering so far and they were very stunted like yours. Let them dry back for a day or two and see where that gets you. And a humidity of about 70% at around 70°f to start then you can drop the humidity and raise the temps slightly over the grow.
The only way to learn is trying, I’m only on my first successful grow and just in the early flower stage so I’m no expert. Make sure to fact check before implementing my advise.

You definitely have to be careful. We had a post just this morning where AI told an individual that curing converts THC-A to THC. It does not. Heat (smoking flower, or decarbing in the case of edibles) converts THC-A into THC.
That said, the information you find here in the forum is 95% valid. We get a loose screw occasionally, but if you see a response from a member that has been around for a couple of years, then you can be assured that you are getting accurate info.
There are a few good YT channels, but much of the advice is just junk from people who will do or say anything they think people will latch onto so they can get the viewership numbers (and therefore payouts from YouTube.)

Droplets of water are the wrong shape to magnify. They also provide cooling, preventing any possible burn. If droplets did have magnifying properties, they are gone (dried up) at the same time the insulating properties of the liquid are gone.

Photo’s or autos? What is the air temperature?
A falling drop of water indeed doesn’t magnify, however a stationary water droplet sitting on a leaf forms a dome structure quite similar to a magnifying glass. Now if my knowledge about energy is right then although the plant may not physicaly burn as the water drop will take the heat, your plant can get UV burn (sunburnt) which may be beneficial in mid to late flower to aid in trichome production but can be very detrimental to a seedling.

Right here is the misinformation that was just mentioned, water absolutely will burn your leaves under strong lights, anybody that says not hasn’t tried it. Leaves should never be sprayed unless treating for pest or disease, that’s it. Then they sit under fans with lights out until they dry.

Haha. I wrote something different (and rather mean,) and then decided I ought to keep it tactful.

Wrong. Science is real.
Water droplets on plant leaves will not magnify the sun’s energy and burn the plants because the leaf surface is typically not smooth and the water droplet shape is imperfect. These factors prevent the water from forming the sharp, focused lens needed to concentrate light sufficiently to cause a burn.
Key factors preventing the “burning lens” effect:
- Irregular Surface: Plant leaves have irregular and often hairy or waxy surfaces. Water droplets sit on this uneven texture, which distorts their shape and prevents the formation of a perfect, light-focusing sphere.
- Imperfect Lens Shape: The shape of a water droplet on a leaf is usually flattened or oblong, not a perfect sphere. An imperfect shape means light is refracted and scattered rather than converged to a single, high-intensity focal point.
- Focal Point Location: For burning to occur, the sun’s rays would need to be focused into a precise, tiny point directly on the plant tissue. Due to the shape and position of the droplets, the “focal point” (if one even forms) is usually dispersed or located harmlessly above or below the leaf surface.
Scientific studies and experiments have shown that the energy concentration needed to scorch a leaf is simply not achievable under natural conditions with water droplets. Damage commonly mistaken for sun-scorching after watering is typically caused by diseases or other environmental factors.

Well, I tell you what you do buddy, start spraying your leaves and crank them lights up and then tell me it won’t.

It takes the right shape lens to focus sunlight. A shape, a drop of water on a leaf will rarely assume simply due to the physics. Any focal point of light will end up below the leaf’s surface due to flattening of the drop.
Please provide photos of water drop damaged leaves from concentrated light. Also provide evidence that plants have not evolved to deal with rain, and include some
personal accounts of any growers rushing around to dry their plants after a mid-day shower regardless of plant species.

Got any pictures of water drop damaged leaves?
You think plants haven’t evolved to deal with rain?
Your assumption demands evidence.

No I don’t have pics, I don’t burn my leaves, but I’ve seen it happen. Been doing this many years, and you don’t get to DEMAND anything . Go polish your rock, water won’t burn it. I know plants get rained on then sun sometimes, that’s not a led light. Outside plants are more accustomed to outside conditions.

You first, skippy. Not just a 9-year-old article by a quack who, just like you, makes unsubstantiated claims that can’t be sourced and verified.

Keywords here: “natural conditions”
We are in grow tents with all sorts of different soil and nutrients not found in “nature”. LED lights (as @Growdoc has said), temperature of water sprayed on leaves vs rainwater naturally landing on plants in nature.
Basically you contradicted yourself, which is fine, but there is no need to argue with people here that have tried and true experience. GrowDoc is a very skilled and knowledgeable grower and they are not just quoting from a random article.
