Hi,
Looks good very happy plants! I believe you mentioned you are using auto plants. From my experience changing the light is not necessary. I use the same nuts and have had good results. I am not sure if you are using air in your grow set-up but you should have a air pump on at least during the time the lights are on but as roots need oxygen I leave it on 24/7.
Just a thought,
Looking forward to seeing more photos.
