Hi. Im trying to figure out the correct PPM ranges for both veg and bloom in hydro. The guy at the store said for soilless to keep ppms 0-500 for veg and 500-1000 for bloom. Is this the same for pure hydro? When I read about the Lucas Formula, it looks like Lucas is giving plants in veg around 1000-1300ppm. If Im reading correctly he's going with about 1300ppm from start to finish (veg through flower).
Can someone please clear this up for me? Thank you.
