Hemps, as far as I can tell, it looks like the amount of carbs you take in a days is what is holding you back energy wise. However taking into considerdation that you are on a cut, it should be expected, include the CNS tax you take with DL going up 10kg a week? You sure as hell burning your energy faster than you build them up.
As for suggestions, the only thing I can think off, is move your carb intake to, after your workout, try to skip the carbs before a workout, because while carbs give you energy, it can also be the cause of you feeling tired/lazy in the gym.
I am currently at 76kg at 1.75m, still bulking, I want bigger muscles before I cut. Currently I am still gaining in strength, but I only have like a whey shake + apple when I wake up, then go to gym. Then after gym I have a massive bowl of oats and another whey shake. Rest of the day my carb intake takes a massive dive, and I only take it in, in smaller quantities. With this method, I managed to gain weight, but cleaner than I would have, would I be taking in more carbs the rest of the day.
The thing is, taking in the carbs just after your workout session, means the body uses that energy to rebuild instead of just blasting it into fat stores.
Other than that, I don't think I have enough knowledge or even wisdom or experience to give suggestions to you.
