I can't recommend it highly enough!! Different ferts for different plants is nonsense....virtually all plants consume nutrients in that ratio - 3 parts N to one part P and two parts K. And it matters not if they are flowering or fruiting - same ratio of consumption and utilization. There are some exceptions, notably a few plants of Australian origin that are P sensitive.

btw, bloom booster fertilizers are pretty much worthless and more marketing gimmick than anything else. Plants cannot take up more nutrients than they actually need and if your ferts are already providing adequate P - which Foliage Pro does - then dumping on more P will not help them to bloom any heavier and can be counterproductive.

I do use a couple of different ferts - actually more in the nature of amendments rather than a true fertilizer - for outdoor, inground plants but there is rarely a need to fertilize them at all.

That was helpful. Thank you. I will try it on a few fruiting plants and see how it goes (old habits die hard, baby steps). If it works well for me, it should be a time and money saver. All the different fertilizers get pricey.

....I also need a few lessons in botany

That is easily accomplished :-) There is an excellent little text - Botany for Gardeners, by Brian Capon - that sums all the necessary info quite handily and in an easily understood manner. It is actually used in horticultural schools as a textbook so not really dumbed down at all.........just not excessively scientific or too technical. Available through Amazon.
