Bubba Kush / White Widow || First Grow

Don’t know what I did to get this growth and greenery.. Was it the adjusted lighting or nutes? Who knows but I like what I see!! Continuing to feed twice a day at 10mL and the new height is 4 ft from floor wit 40% power. Future plans: to attempt to lst and top the bubba kushes and do light lst on white widow to keep canopy even?? Questions: when should I transplant?
