When i mist them, i pull them from under the lights, and mist for anywhere between 15 - 20 minutes. I mist when the leaf is not holding water anymore. Before i put them back under the light, all the water on the plant leaf is gone, this will last about an hour or so. My thought is that since they are under a 400W MH that the hour or so they are not there will not hurt them. These plants are only 15 days old.

If this is pH lockout from the soil, would a flush take care of the problem or am i better off just going with a soilless mix and disgarding the premix that they are in now (it is MG premix and i have seen alot of people having problems with that).

Thoughts and opinions are greatly appreciated since this is my very first grow
