How do I Fix?

The inside of my plant is starting to wilt. I think it's about to start the flowering stage. It's just been in dirt with some solid I picked up at HD. The sprinklers water it nightly but I was giving it extra water with the hose weekly and let it go to long last week. We did have a hot stretch in my area.

After reading about how I took care of my plant I'm surprised it got so big. I did Trim the plant 6 weeks ago and got some roots to sprout on the "clone" which is about 2 feet tall now

Yellowish looking and reads like it gets too much water. I'd maybe block a sprinkler from watering the area so it can dry. I'd want to know the pH of the soil in the rootzone and adjust if needed.

Cap the sprinkler head. Manage the watering. Defoliate the lower stuff
