Feeding / Watering advice appreciated

This is my second grow. I have everything in soil and my routine has been misting the leaves 3 times daily with a 1/2 teaspoon of Epsom salt and water mix. Every 3-4 days I give them about a cup of miracle grow plant food directly on the roots. They have really taken off in the past couple of weeks and seem to be thriving. I have a few plants and some are different ages, maybe by 2- 4 weeks, not sure exactly. I'm wanting to clone this weekend and cut the lights back Monday. None of the plants are less than 12" so I'm confident they are ready for 12/12 ( See my pics in my profile and see if you agree) I have miracle grow that is for flowering. I figured I would feed them about like I have been and every few days mist the leaves with the miracle grow solution and continue to mist with the Epsom salt water solution. If any one has any tips or advice it would be most appreciated. Thanks!

1st off dont overwater or over nute. Second throw that miracle grow shit in the garbage an go to the hydro store an get yourself some liquid nutes.I myself have been usind Sensi Veg an bloom 2 parters.And they friggin rule.

As for misting waste of time unless there still in the clone phase.

Yeah, I realize that I can get much better stuff than what I got, but really when it comes down to it, the basics are the same. I just posted some new pics and as you can see they seem to like something I'm doing. I'm more concerned about the flowering stage at this point
