Sounds like a good plan. It helps to look at veg and flower as two completely different stages. Whether or not you have your plants at "maximum" nute levels during veg will not affect your yield that much. It can affect the rate/speed of growth but that is about it. That's OK because you can veg longer if you need to. When you get into flower is when you really want to keep the nutes as high as you can. You have a certain amount of time for flower and then that is it. You can't lengthen the process. Well it just so happens that bloom nutes will not burn your plants very easily. Veg nutes are high in nitrogen making it easy to burn but bloom nutes are very low in nitrogen, instead being mostly potassium and phosphorous. Good news is that it is very hard to overdose on P and K. Any excess of these two nutes will stay in the medium and be flushed out with the next watering. Unlike nitrogen, the plant will not absorb more than it needs. So all of this was basically a long way of saying that 1/4 or 1/2 strength will be good during veg when you are using veg nutes but when you switch over to bloom nutes for flower don't be afraid to go up to label strength at that point.
We can get into the "rootbinding" debate later. Personally, I think this concept applies to indoor growing only when you are transplanting - and even then it takes very tightly wound roots to choke out a plant. That's what rootboud really means. A plant's rootball is so compact and interwoven that it becomes a barrier to the uptake of nutrients from the surrounding soil. But indoors we pour the nutes directly on top of the roots unlike outdoors where much of the nutes come from more distant surrounding soil. The exception is when we transplant to bigger pots. There is now new "surrounding" soil around our existing rootball. So my point is that big pots indoors don't make sense and transplanting any indoor plant more than once makes no sense, and as a corollary worrying about rootbindig doesn't make sense. I've grown 6 foot plants in two gallon pots filled only 3/4 of the way up. That's 1.8 meter tall plants in about 5.6 L of soil volume for my UK friends. I've seen 4 footers in 500mL containers. As long as you are providing nutes on top of the rootball and not to unrooted surrounding soil then you are good.
