Crictical Purple

the girls are coming along nicely,, i cut out all the nutrients except the bloom and cal-mag, the smell is getting more and more. I was suffering a cal mag issue so i uped the calmag to 1 1/4th tsp. they seem to being doing alot better and i havent noticed any worse probs with the cal mag. The two out of three plants are showing signs of color changing pistels but the third one is not showing no signs of color yet,, time will tell,,
