My white widow auto and chocolate skunk auto flowering. The glueberry is showing lots of pre flowering so I’m assuming it will be flowering any day now. The choc skunks leaves have gotten lighter and now are purpling. I fed it the correct fox farms nutee and added flower fuel. I think it might be light stress but my Lights have been 18 inches from the top of the canopy. Fed the flowering plants with flower fuel and tiger bloom.
