I've not tried the liquid eart nutrient, but Zandor the great has said he uses GH series .
There is a post for Lucas formula using these nutrients.
The formula does not use grow. I tried the gh3 last night and was amazed at the stretch I got in just four hours, after changing nutes. I quickly changed that out and am using the lucas formula. I don't want tall spindly growth.

The lucas formula is Grow 0 Micro 5ml B 10 ml vegetative stage
0 8ml 16ml flowering
