26, 6'0", 215 Lbs, 15%, Macro Breakdown

Hey guys! So Ive been lifting for 7 years now and want to start prepping for a bodybuilding competition next year. Im in the military so its kinda hard for me to hit my macros but when I can, I do. I know its kinda stupid to go on and off of dieting but I have no choice with my current lifestyle.
So Im planning on carb cycling and know that I need to hit my weaker muscle groups on high carb days and my strong on low. Im planning on this split…

Monday-High
Tuesday-Low
Wednesday-Moderate
Thursday-Moderate
Friday-High
Saturday-Low
Sunday-Low

I found my lean body mass and broke down my macros using that number, not my current weight. I train 6 days a week and plan on doing steady state cardio 3 days a week, 30-45 minutes, in the morning on an empty stomach, 2 days a week post workout, 20-30 minutes and HIIT 2 days a week, post workout, 15-20 minutes. My workouts are pretty solid so I don’t have to worry about those. I was just wondering if anyone thought that this macro breakdown is a bad idea. I will be eating 6 meals a day. already have the meal plan ready. Just would like some advice before I start. Thanks Guys!
