Don’t worry about those lower leaves. It’s normal for the plant to shed them as the plant matures. The plant looks fine overall.

Agree with @MidwestGuy guy and would ask if you’re using the Grow Big with the Tiger Bloom :love_you_gesture:

You can go on Amazon and purchase build a soil- clover cover crop and help with lots of things including nitrogen. I use it and works great.
I use lots of build a soil products. Grab a bag of there top dress soil kit. It’s awesome. Even has a few red wiggler worms inside.
