Do you have stock in Fox Farm or what, bud?

That's a ton of nutes, and that's fine (although not economical for me:smokin

I'm sure you could mix the (half strength each) grow big and big bloom, but the question is: why?

It sounds like you've got 'em separate and you're alternating products at feeding, which is exactly what I would do. I'm sure most would say the same, but maybe not.

However, I think you'd do just as well with only one or the other. Don't take my word for it though as I've never used FF nutes, do some more searching for those doing the full FF routine.

Personally I would do mini-experiments on a couple of plants of the same strain with different nutes to see exactly what results are more preferable, or just see what other FF people do
