Opinions on Kind Soil + Nut

[yamiacaveman]

I have 2 Auto Northern Lights, so far very healthy, using and growing the Kind Soil way. In a few days my girls should be into the flowering stage and also due for some water. I have some Tiger Bloom and was wondering if I should or could add it to my next watering. I believe the idea with the Kind soil is that you don't have to add any nutrients but I also know know members here experiment a lot.

So do I add some Nutrients or just let her go!

Thanks for any opinions.
