do you mist your clones daily, i mist mine about 5 times a day and if im at work, i mist them soon as i get up, and then once again befor i leave and then t wice when i get home, and then once befor i go to bed, it works for me, I also mix my spray with willow water and kelp spray, the willow is loaded with rooting hormones( hence break a brance from a willow tree, jam it in the ground, poof a new tree) the kelp helps to regulate any Nutrient defecienys ( i know, i suck at spelling), sea-boost will work too if you cant find pure kelp juice.
