That looks to be light burn.
It’s from water being on the leaves. And the light magnifying causing it to burn. I notice water on the above pictures. Try not to get water on the plant unless the lights are off. Lightly soak up the water with a paper towel if and when it happens.
As for if it being a male or female It isn’t showing any signs yet.
So far everything looks good though just watch the water on the leaves.
