Plant problem!

The leaves on my plant are turning yellow and they have spots (black or brown, sorry im colorblind) so I keep cutting the bad leaves off but its happening more and more everyday, I already pulled the other plant a little early because of this (it was getting really bad) So I guess my question is does it sound like something that im taking a risk of losing everything by keeping it going should I pull it? or should I keep cutting the leaves off, or should I leave it alone? what do you think is wrong with it?

What nutes have you fed it? What are you in soil?

This used to happen to me in hydro until I got some cal mag.

could be nute burn but hard to tell with out more info and pics

Pics will definitely help. IDK.
hope you get it worked out!

This is my first time growing pretty much, Its outside in regular potting soil and I didn't give it any kind of nutrients since it started flowering. I'll try and get a pic when the leaves do it again (right now all the bad ones are gone)
