Also depends on the size of the plant and the genetics. I use the whole line of Botanicares products but my plants like medium ferts so I am running 650 ppms on the 3rd week of flowering. Mine are also in hydro and not in soil. There are lots of variables to consider but I like WH schedule. I just have to use less due to my plants genetics. Start low maybe 1/4 to 1/5 what the bottle says and go up by no more then 30% at a time. Just look for burn and how the leaves react. That line is some great stuff though.

Cheers!
JeffersonBud Reviewed by JeffersonBud on . Botanicare Feeding Schedules? Hey everyone I know Pure Blend Pro Grow/Bloom are well-respected ferts so I picked some up (along with some Cal-Mag). I have to yet start using them, and in the meantime I'd like to find out what you all use for feeding schedules with these little guys. They'll be under 400w HPS in soil. I'm aware of the necessity to dilute the ferts, but by how much and at how many weeks/months in do you change it up? Thanks everyone. Rating: 5
