First grow LED 2x4

My middle plant is starting to get really dense nugs, the other two still appear to be swelling up. plant 3 at the end that had very airy buds before is filling out. It turned almost completely purple on the leaves what seems like over night , the plant on the very left is a royal dwarf I thought would be smaller, it’s grown so tall it has shaded the sides of the plant so I’ve had to use some led strip lights on the sides to light up the dark spots
