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!
