I'm curious. Why not? I thought it was a pretty good answer, but maybe there's extra info we're missing out on?
One thing you should consider though is that less is sometime more when it comes to fertiliser...and overwatering is a common cause of the "claw" problem...
In answer to your question, more phosphorus does not = more bud/potency.
Genetics will be the main factor deciding how big and potent it will grow. You simply need to provide it with enough of the light, nitrogen, Co2, phosphorus etc that it needs to maximise its genetic potential. There's really no point giving it more nutes than it can use. In fact, the extra nutes will build up as salt in the soil and you will end up with lock-out problems. Similarly, if you give a plant too much light you can end up stunting it. Less is sometimes more!
So the point is not to force-feed your plants like they're sumo wrestlers. Just give them enough so that they have all the chemicals they need to get on with the business of growing to their maximum potential.
