Need Some Help. (flowering)

I have a plant 30 days into flowering (what I believe to be an autoflower but seeds unknown) I have some yellowing and some browning in my leaves. This is my first grow but just want to some advice to what might be causing this and maybe how to fix it. My pH is good.


Thanks, Brokebudz

soil, lights, nutes, when you fed last. These are things we need to know.
