Advice on best specific bulbs for a t8 4ft fixture and my setup

I just setup a 3x3x5' flower tent. I have 4 2 bulb t8 shoplight fixtures by american flourescent with a mixture of 4100k ecologic octron sylvania bulbs(total of 4) and 4 zoomed bulbs(coral sun and flora sun, 2 each) standing vertically in the four corners of the tent. In the center I have the galaxyhydro 300w dimmable led. Have an intake and sortof exhaust fan setup. I'm looking at flowering a total of 7 girls in a scrog method involving tomato cages with a squared out screen secured to the top of the cage. My idea is to move them around everyday to encourage even growth. I'm already looking at upgrading the led to the marshydro reflector 192. I might even make the move sooner than than later. Im going to be using fox farm potting mix, but was interested in any recommendations on a custom mix or nutes since as of now im using a sample kit branded David's grow. Looking at using 5 gallon grow bags too. Looking for suggestions on bulbs and any lighting in general given what you know already about my setup. I'm not blowing a ton of cash on this setup so please be realistic with any ideas to improve the various parts. Thanks for all the ideas. Now let'er rip!
