Lucas Formula 5/10 or 8/16 with LED ?

Lucas says to use 5/10 ratio with cfl and 8/16 with HID lights, but what about LED? Would that also come under the 'HID' category ?

Just set the EC to 1.2-1.4.

Yes.

I do 5/10 lucas formula throw some terpinator in there if you want and some epsom salts lol.
