Zombie Kush x Purple Punch Micro Grow

she finally in bloom stage, the last one in my micro grow set-up In picture was D4 from the 1st pistil show, still not stretching much. the leave look healthy and bushy but it's not explode like the other 2 plant in the beginning of their flower. 850 ppm is what i given to her right now. Next weeek will pump it up around 1050-1100,
