No and I am not sure how well this would work either. I just used a mixing chart that I once had. Just search the web for "ppm calculator" and this should help get that "recipe" correct.

I suppose that after you follow the recipe from a ppm calculator you could test it with a PPM meter for shits and giggles but not sure its nessesary. Nore am I sure of the accuracy so useing a calculator and measuring your mix would be the way to do things.

**edited to add**

Now when I said 100ppm or higher this is sort of just a guideline. I have gone as high as 500ppm and as low as 75ppm but I also had some strains not hermie with the lower dose and I also had some plants that were quite adversely effected with a strong dose. Hence the reason to experiment if your attempt totally bombs its only costed you a bit of time and wasted 1 clone so keep at it and dont let minor setbacks stop you.
