Yes, I've ordered a TDS measuring wand, but in the meantime...
There must be a formula to calculate ppm when using a fertilizer.
Case in point:
I have FF Grow Big (6-4-4) and if used as directed, adding 1 teaspoon full per gallon (assume neutral/distilled water) how many ppm of the three nutrients would be in the gallon?
If pressed (ie, a final answer on Jeopardy) I would guess one figures out the "weight" of one teaspoon full then calculate 6% of that and the "weight" (volume?) of the water and do the math... But I also thought there might be a calculator or converter online.
Does anyone know or have a link?
thanks
