ppm a tds meter is used for messuring the part per million in water

This is going to sound stupid but can someone explain what this chart means as its like a drawing from albert einsteins (sp) book of plans or something lol, i know i know its easy to understand when you know how so thats why i am asking some kind person to explain it for new guys like me

The outer 2 columns are levels of nutrient strength in the water, measured as a Conductivity Factor (CF) or Elecrical Conductivity (EC). The inner 3 columns are the equivalent in Parts Per Million for 3 different makes of meter.

sorry this would prob help lol just had a wake n bake so not really with it give me half hour two more j's n some more coffee and all will be normal again. im growing in coco with canna a n b nutes with canna boost and using bloombastic towards the end and have been getting around 3 n half dry have been growin a sativa strain but this takes up far too much room so have just germinated some barneys lsd n blue cheese want to see what there like. ive been giving them the mixture that it tells me on the back but still think am over nuting as leaves look like they have nute burn from what ive seen on here.

hi peeps i have a question regarding the table ive just got a new meter and calibrated it and ive found out mine is the truncheon one....

now ive seen on a dvd i watch never to go above 1600ppm...

now looking at the chart my ppm level is alot higher than all the others so can i only go to 1600ppm with or say can i got to 2240ppm as this is 1600ppm on the hanna chart?

i hope some one can clear this up for me
