Not sure about ppm but Happy Frog already has organic nutes mixed in. You shouldn't need to feed for at least 2-3 weeks.

ppm is parts per million on the nutrients. i'm sure by now the nutrients have been sucked dry from the soil. i'm just trying to figure out a good measurement of nutrients to put in the water. know any reference sites?

Pretty much just plug in your reservoir size and what type of feeding program you want (light, heavy, etc). Should do the rest. It will give you a week by week feed as well as ppm peak. I always do less than they advise or do a smaller res size because they kinda overdo it. Also, I believe (could be wrong) that unless you are using RO water, your ppm will automatically be 100 higher than what theirs is.

I use advanced line and Happy Frog as a matter of fact so let me know if you need anymore help.
