well, most bumpy rides can be prevented as we learn to adjust things, the few drops of nutes could easily sent little ones over the edge with ffof, ,, fox farms was meant to be water only for weeks,
on my grows with ffof I have had bugs,, but it was not the fault of the soil on mine,, I had mites 2 grows ago, but they rode in on the clones, and it was nothing that mitacide like floromite could not take care of easliy and it sure did take care of it,
knats and other buzz kills are easily taken care of with some azamax, ,, azamax is cheap and you can either spray it on,, or what I do and others is a soil drench, if there are any bugs in the soil,, azamax takes care of them
on future grows, I will be spraying and soil drenching right from the start, even if I dont see any bugs, its just a preventative,, do it early in veg and you wont see critters the whole way,, many people take such insurance measures and dont mention it,,
I have a friend who is on his 5 or 6th grow now with fox farms soils,, he tends to prefer the happy frog, so he can ad nutes later in flower,, but all of his grows have rocked it,, sure he had some bugs and even powdery mildew,, and those were taken care of easy with some sprays,, cant blame powdery mildew on the soil,, its an airborne
