PPM...

is she growing hydro?

how old are her plants...

PPM.. should rarely go over 1300-1600... depending on the nutrients you are using and how well you know your plants and where they are at in there growth cycle..

youngsters in hydro... new clones.. freshly rooted.. should start around 200-400....

she needs to watch the tips of the leaves and make sure they do not turn brown...

as she gets more in touch with her plants she will notice that they tuirn a very very dark green when they are getting to much FOOD!!!!!!!!!

etc..
