Hey everyone. My seedling is about two weeks old. Haven’t fed at all yet. She’s in an organic soil and on an 18/6 light schedule. I noticed a thin spot on one leaf and I’m hoping it’s something I don’t need to worry about. Here are some pics…

Minor issue. Don’t overwater and you should be fine. Those leaves will eventually be cut off anyway. Great start.

Thank you! Crazy how much we come to love these plants haha. When should I start feeding her? I’ll be using Flower Power nutrients.

You can get by with water until the plant has 3-5 sets of leaves.

Looks to me like water droplet light burn not a major deal try to keep water off leaves during lights on time. Otherwise looks good happy growing

Saw you had organic soil. Some grow start to finish in their base soil mix. Others may help out in this area. You might want to detail what you used. @garrigan62
@anon46981397 that makes perfect sense because I noticed a water droplet on my leaves a couple of days ago and thought nothing of it. The water would cause the light to be magnified, thus burning the leaf up. Thanks for the heads up on that.
This is my soil of choice:

That soil should feed for the first bit almost until flower. Watch your plants leaves for signs it needs nutrients then feed

I trust you have a tds and ppm meter and have done your research watch ph levels try to stay 6.5 to 6.8 ph for best results in soil

I had to save it so I had it when I needed it. Its critical information to have in an emergency situation.

I agree with the others, minor issue not any concern right now. I’m not familiar with that particular soil, but it should feed plant for at least a few weeks.
Do you have ph and tds meter? You should be making sure water your plant is getting is in proper ph range for your medium. When your plant gets a little larger you can water it to runoff and then test the runoff to get an idea of where the nutrient charge may be.
To determine when your seedling is ready to be fed, check the cotyledons; once they start to yellow/dry out, it means you need to start feeding your plant.
From the spots and twisting, looks like a pH issue might be starting, and possibly your temps/rh need adjusting. Not a big deal, but if you’re growing an auto you want to get everything dialed in quickly to prevent stunting it at a critical point in its development.
What strain?
Type of soil?
PH of input?
Temps, day/night?
RH, day/night
Type of lights? Wattage? Height from plant? Daylight/dark?

I’m having same issue, it’s so stressful, I’m using coco coir an ffof mixed. I watered last night like 2pints, but today 2 of 16 plants got tips curled up an wierd spots. Smh. Maybe I got water on leaves or to much water maybe, there small plants like 8intall seedlings. Idk hopefully its ok.
