Never go about 1600 ppm. And with that I think you need to be running CO2 to run it that high.
GH says 1350 I believe.

I'm at 1300 with my Super lemon haze and could probably go a little higher. I can only get up to 950 with my Strawberry haze without burning the shit out of it. So deffinitly depends on the strain.

sounds like an OK ppm but really if you are looking to maximize it depends on a host of factors.. transpiration rate, total plant mass, humidity, PH, light intensity and spectrum.. etc
for instance if humidity even changes by 10%, then the same percentage change in ppm (plus or minus) can harm a plant (osmosis ratios change as logarithm to humidity - not linear) - (depending on initial levels and other factors combined).. PH --> for instance 5.8 (most nutes can be absorbed so increasing ppm by 100 can have significant results, but PH of say 6.2 and to have same affect, ppm would have to be increased by at least 200 ppm or so because at the higher PH the extra nutes may have a significantly decreased absorption rate.. etc / etc / other factors have similar effects (10% greater total plant mass will have generally a 20% increase in trans rate which could make only a 50 ppm change cause nute burn).. not to mention that differing NPK ratios cause different levels of soluble potash to be absorbed and used at different rates causing an increase or decrease in waste products causing the slightly elevated ppm to become a huge problem.. get my drift.. have to toy with it and find exact max level for individual plants.. good luck man
