ppm?????????

i cant seem to find a muppets guide to pmm lol

so could some1 help me and explain what i'll be aiming for in what stages of growth

c'mon

look up lucas formula, pretty basic and works well, all you need is maxibloom and floramicro both by general hydroponics, used in soil and hydro, im currently using maxibloom and koolbloom in late flower

yh im using lucas formula atm...
just dont know where i need to be ppm wise??? what sort of ranges to work with???

900ppm is a good ppm
1200ppm for the stetch
