Demand for extra phosphorus and potassium besides what base nutes provode in any stage of flowering is over suggested...over rated...and over used. At the onset of flowering and about 10 days into 12-12 most cannabis strains like a nice small bump in P if that. Plenty in the base nute but you can up it a bit. Actually if you use a Phosphoric Acid as your pH down and depending on how much u use to get pH down...should be plenty. Towards middle and late flower most plants could use a small kick in K. And magnesium. Just a touch. And preferably in tje form of potassium sulfate and magnesium sulfate. Again..should be all set if your using a Bloom base nute. Those comapnys know what they are doing if the Bloom base has upped the K and magnesium in the form of sulfate. That should he a slightly higher number as well if your using seperate Grow and Bloom bases. P/K Boosters were not really common back in the 80's and early mid 90's and we grew just fine with Grow and Bloom base nutes alone. Personally I think growers these days over use them and think they get bigger better buds with them. If you wanna really get plants going in flower you wanna use kelps high in the hormone cytokinin in early flowering. This gets em going. Slows the stretch down..makes side brances grow and earlier bud set. Using a silica with a fulvic acid can help reduce stretch as well as strong branching too. Playing with temps lights on and off is the ultimate stretch stopper though..short of using the toxic PGR's like paclobutrizol. That shit was meant for roses and other greenhouse crops that humans dont consume. Stay away from that shit.
