MG all purpose ferts are working for me, as well as MG moisture control soil.
Without details it's hard to say, but general rule of thumb, you shouldn't plan on feeding for at least first 2 1/2 weeks.
You can go to Lowe's, and get some nutes from the seed department, it comes in a little envelope, made by Burpee. It is a 0-15-11.
When you get a few weeks into flowering, you can add this to the MG, along with some Unsulphured molasses.
