Which nutrients

Your npk ratio in vegging is 3-1-2. In flowering it shifts to 1-2-3. In coco you want a run off ph of 5.8 in vegging. Then about 6.2 6.3 in flowering. So good water ph pen, and calibration solution kit is required. My green crack diary is in coco perlite and growstone. Grow stone is not required. Coco needs to stay at 90 to 100 percent saturated. Maintaining your substrate is key to a strong grow. Will require lots of water at proper ph level. If you need help feel free to message me. Any nutrition can work just likely not right ratios. Multi part base nutrition has been good to me. Then a bloom boost high in potassium and phosphorus is required in flowering for denser and potent buds. Try to maintain a 83 degree F temp with moving air.
