What is this?

Hello
I have a autoflower in a 3 gallon pot with fox farm ocean Forest soil.
She will be 4 weeks old tomorrow.
I seen this on the lower leaf.
What is causing this and how to fix it.

That leaf is expendable…. ( early leaf ) …

If rest of plant is fine - carry on.
Clip it.

Thank you for the reply.
I am trying to copy what you did with autoflowers just in ocean Forest soil.
Tomorrow will be week 4.
What week should I feed with more soil or feed with Dr. Earth.
If dr. Earth how much should I use

As said, I'd remove it, it's not going to get better. My only suggestion would be watch your watering habits, it may be little too wet.

Thank you for the reply.
I only water 1 cup of water about every 3 or 4 days

Here are pictures that I just took when the lights came on.
They will be 4 weeks old tomorrow.
I am using a mars hydro ts3000

Is there anything I should do differently?
What setting should my dimmer be at?
What height should my light be above the plants?
