Heat stress ?

Hey guys, could you give me some advices 1st time growing (autoflower Royal Haze) and as you can see 2 leaves are somekind of curling up, I was reading it could be heat stress but it started happening about 3 days ago, I mist it few times a day and fan is blowing on it all the time so no ideas what could it be (using 300w led light, biobizz light, no nutrients yet, 2weeks old)

It'll serve us better if you post pics with a more natural light.

Also. The more information on environment. Feeding, watering, pH's and the like. The better we can help you resolve your grow issues.

U need to give more info., Like u say it could be heat stress but u dont provide temps or humidity?

Depending on how close to the light and how confined the space is. It might be getting a tad warm.

To find out how close is too close. Move your hand closer to your lights till you can feel the heat from them. If you were to mount your lights less than that distance from your plants. You'll likely fry them.

As far as temperature goes. Basically. If you couldn't handle the environment your plant is in. Neither can it. They don't like the cold. Nor do they like excessive heat.

Okay thanks for reply soil Ph is 6,3 fedding only with tap water for now, temp is 67F and humidity around 50-60%

Then no worries is just genetics stuff that seedlings does. I get that and twisted leaves all the time and then they sort themselfs out., Try to get those temps to 70-75. U say 67 thats at lights on or off because if is 67 at lights on at lights off it will drop too much

Thanks a bunch

What kind of soil is that?

Biobizz light

The temps are when lights are off

Looks fine to me. But why so small after 2 weeks?

Should be 6 inches with 4 sets by now.
