IMO high P foods are not desired at ANY TIME when growing in containers. The practice of high P foods for flower/bloom is a bleed over from Agriculture to Outdoor Gardening and very mistakenly applied to indoor/container gardening. The reason for the high P in Ag is P binds very regularly to organic materials and leaches away quickly causing deficiencies. So farmers combat this by upping the P and it worked. For a while. Then they found that they would have to do all sorts of extra work later after years as the soil was now P contaminated and leaching into ground water. Now they employ much smarter practices. But it's foothd is strong as it was the way for so long.
Now this was also caressed by indoor growers. And cannibis growers in complete error. First the P does not leech off in containers like in outdoor soil and it does bind at near the degree it does in outdoor soil. Even more interesting is that of all the Macros Cannabis uses P the least even in flower. It uses three times more calcium in flower than it does P! This all from plant tissue analysis. Most of the time it is this mistaken practice of high P foods which causes the premature leaf loss in flower that so many think is normal. In actuality if cannabis is properly fed and grown the leaf drop signals that it is past it's prime and sesanence or annual death after anthesis is occurring.
