I personally would 'recommend' Big Bloom only, if you're growing in organic soil like OF and want to stay organic. I almost feel like I have to preface everything with an in-depth explanation here because too many people simply don't understand organics: they think of it as some kind of buzz word, or that it has only to do with things being "all natural", or assume it doesn't matter to the plant. The essence of the matter is that soil in nature is far from inert, it's actually very much alive, and the life within it nourishes the plant in more ways than just breaking organic matter down into ions which are plant available (which is highly significant in itself). When you buy a 'soil' like Ocean Forest you aren't paying for dirt. What you're really paying for is all of the natural amendments and ingredients (and mixing) that go into it to make it soil-esque, otherwise it would be a regular, sterile, run of the mill soil-less potting mix (e.g. sphagnum peat, perlite).
Instead it contains actual sandy-loam along with forest humus, other living, and a plethora of all natural, ingredients that depend on the life in the other living amendments to break them down thoroughly into a form that is plant usable. Forest humus is very rich, decayed organic matter that is teaming with life- much like earthworm castings which are also in OF. Other sources of life in OF are the additional compost and bat guano. Chemicals in the Grow Big and Tiger Bloom at the very least make the microbes lazy so that they wont feed or provide so much for the plant anymore and you have to keep applying the chemicals. It can also piss a plant off (shock, set back) to go from having microbes do so much for them to there not being so many microbes.
The only reason I would even 'recommend' Big Bloom is because I know it is the only actual organic bottled liquid nutrient that Fox Farm produces. I've heard plenty of good things about it but when I thought about buying some myself I was put off by the price tag. It's a low NPK organic nutrient with a higher ratio of K, and it has microbes and some extra goodies, so it does certainly have some desirable features. But if all you want is a convenience as well as organics I would point you in the direction of the Fox Farm's Peace of Mind line of dry nutrients; if you demand liquid organics I'd point you in the direction of Earth Juice.
