Yellow leaves

I have 2 plants in one 5 gallon bucket and I notice the fan leaves are turning yellow. I heard its not the best to have 2 plants in one bucket but its to late to try and separate them. I havent topped them or anything I'm just letting them grow. It's in early flower stage and im growing them out doors. This is my first grow and need a little advice on my plants. I give them flora grow and sensi cal mag extra. I feed them once a week on Friday and give them half of what the bottle says to give them. I also have worm castings as a top soil for the plants. Should I cut the yellow fan leaves off? Any good advice would be appreciated thank you.

You will generally find when the lower larger fan leaves are starting to turn yellow and go brown they have expired or done a job for the plant, in my opinion remove them, because the plant is still supporting them, when the plant could be using it's energy elsewhere

That's what I was thinking to thanks
