Both sprouts still have the shell attached......one worse than the other.
Spray with water to soften, then very gently pry off with a toothpick or tweezers........don't leave any membrane either.
If you don't remove them, your sprouts may not survive.
I'm not sure why people panic over a few seeds.
In the 60's and 70's, every bag of weed I bought had seeds........lots of seeds.
It was still good.
Killing a healthy plant over a seed pod is ridiculous.
How old are they actually?
Originally they were 20 days old, then you switched to 13, then you switched again to 10 days old, then you switched to 11 days old.
Which is it?
Beautiful plants.........well done.
Temps should be in the low 80's and humidity should be around 50.
Length of flowering stage depends on the strain..........I rarely have a plant finish in less than 10 weeks.
Good luck.
