Pineapple Express & Gorilla Cookies

Hi guys, Weel 6 here. I has a few problems with my babies, as I added one more light LED to my garden. The one I had before it was not good so I decided to add a good one (LUMATEK ATS200W). However, they stressed out because of the heat and light burnt (you may see pics on the questions I published). So I removed the other light and left only the LUMATEK, and I guess it has improved. Also I have been overwatering them, so I stopped watering them for 3-5 days and after this I will add more nutrients and adjust pH back to 6.3. Any suggestions, please feel free!
