Seedlings have yellowing leaves and a two stalk plant

These 6 seedlings are 1 week of sprouting and I have been using a dome under FC 3000 light at 25-30% about 16 inches above the plant. The temps are 81 during the day and 76 at night. I noticed a few yellow tone leaves especially on one. Is this normal? I also have a two stalk plant. Should I let it continue with both stalks? I have been misting the domes and spraying the sides of the cup every few days. They are in Happy Frog. I took off the domes today. This is my first grow and welcome advice :blush:Processing: 681671DE-B4E1-4876-82B6-928E3611B204.jpeg…

Seedlings at that stage need only a couple ml of water a day. Let the soil dry out before you water them again. Suggest one plant per pot.

The double plant came from one seed. I plan on transplanting them when they get bigger. I guess I’ll just see what the two stalk plant does. I’m afraid to cut off one of them

Is this what you are referring to as a double stalk? It looks like 2 separate plants to me. Did you drop an extra seed in that cup? I’m pretty sure that is 2 separate plants based on there relative size…

Grow it out see what happens, As mentioned seedings only need small amount of water.

It was definitely one seed

Congratulations you have twins. Looks like Danny Devito and Arnold Schwarzenegger to me. Ha

Eventually you will have to separate them, even if conjoined. I usually wait till the first set of leaves past the cotyledons set out. Maybe a week more give or take a day.
