So when test my Lucas formula of 8/16 it comes out to 1560ppm and my tap is 200-210... does that sound right? Lucas formula for floros of 5/10 reads about 1160ppm.....And if I mix up aggressive growth formula from GH 3 part (2-3-1) my TDS meter reads "out of range" and my range should be up to 1990ppm - I know pretty close to nothing and any advice would be greatly appreciated. - thanks

well if the Lucas formula is 1326 with a starting point of 0 ppm then it would make sense that my reading would be 1530ish since my tap is 210... does that sound right?

WHAT DOENT SOUND RIGHT IS THAT EVEN AT A BASE OF 0 then adding lucas it coming to 1326 seems high although lucas does say to not count the tap
ppm so at 1326 you will be fine

I use lucas but i run aeroponics and it requires a far less ppm..

Young plants for me only need about 250-300 ppm
