Need some help. Yellowish brown color leaf?

This is the only leaf Ive found like this, and its at the bottom of the plant.

This is the only leaf Ive found like this, and its at the bottom of the plant.

More than likely humidity its high and plant is sweating. Do you have a fan blowing on it?

 

[BBoomer]

I do have a fan on it, humidity is about 40-45%. Im 4.5 weeks into flowering.

My guess is sweating because it lines up with the leaf behind it. But keep an eye on it and if needed defol lowers.

Awesome, thanks!
