I think it would burn the plants and possibly stunt the growth.
I don't use a grow/veg formula in flowering.
I just use Pure Blend Pro Bloom for soil...and Budswel.
In veg I use Pure Blend Pro Grow and super thrive.
I think adding all that crap is over kill.
It doesn't make enough of a difference.
Maybe for hydro. But not organic soil growing.
Fox Farm products are very good.
But a tad expensive.
I use there soil.
But Pure Blend Pro makes a killer bloom nute.
And the Budswel is just sea Bird and bat Guano to add to the flavor and fatten up the buds.
I think adding the veg nutes in flower makes the taste crap!
