Aqua Flakes a&b for soil?

Hey guys first time poster and I was curious if anyone had used Aqua Flakes a&b with a soil medium as apposed to and sort of hydroponic system? If so I would really appreciate some feedback and how it went, how much you used during flowering, and any additives you combined it with. Thank you ahead of time.

House & Garden has Soil A & B for you. I wouldn’t use Aqua Flakes as the N-P-K ratios won’t be right and your plants may not like it. All the other additives, however, are fine to use with soil or hydro. …Peace and good luck.
