The White OG x Cream&Cheese (White Nova)

White Nova is going well growth has exploded into flowering. I'm a little worried how close the tops are to the light as I can't raise them any further. Probably should have flowered them 1-2 weeks earlier. Flowering is well underway. I am going to snip more undergrowth than usual because of the crazy thick canopy. Basically no light penetration to the lower sites. The base is so dark little roots are trying to grow at the very bottom of the stalk.
