Hello outdoormaster, your girls are looking great.
I cant see it on the picture but i understand your bottom leaves are yellowing up and rust spots.
From what i can see you do a little lst.
I recommend to open her up more and make sure there is enough airflow going through your plant and also the light reaches to the bottom leaves.
Also what kind of nutrient are you using.
I strongly advice to ph balance your feeding water around 6.5 for veg and more around 6 to 6.2 in flower.
Hope this was an helpfull answer. Keep on growing my friend.
Peace 👍
