Yea she looks healthy Mr. North.  Different nute lines have different ec/ppm recommendations.  Fox Farms ppms are like crazy ass insane.  I'm giving GH Flora Series ( Micro, Grow, Bloom and Liquid Kool Bloom,Silica, Cal/Mag, Blackstrap Molasses) a go for my next few grows.  Using the aggressive feeding schedule, so far I haven't seen even a hint of nute burn what so ever.  Also I have always only worried about run off ppm's when I had issues with the plant.  Never understood the ppm when feeding.  So when the ppm's aren't too much you had water, if not enough you add more nutes?  and then which of the nutes would you add to bring up the ppm's?  Anyways that's just me.  Happy growing.
