The levels of P-K really do not need to change. The plant uses a bit more P in flowering but does not mean you need more. Switching numbers can cause stress. Since N is tasted in plants more it is best in my opinon to gradually cycle off from a 16-5-11 to a 8-5-11 at the end of the cycle. Plants use the most N then K then P and have the ability to store P more then either of the others. It is best to feed at a constant to reduce stress.
