Lucas Formula in soil?

[IrishBoy]

i am in a soil-less mix called Sun Shine#4. i am doing the Lucas Formula right now but am only in week one of flowering. i have never seen a soil grow using the LF, so i am wondering will it work with soil and have good results? any feed back will get a rep point for the help.

thanks!

it should work. what Formula did you get hard warter? the hardwater formula has less calcium in it, as most hardwater has lots of calcium in it.
