So the lighting you have you don't wanna go based off wattage equivalencies. You wanna go off what they draw from the wall. 150w cfls usually draw about 42w and I looked up that led and see no info on the actual wattage which is a red flag that it's not a very good led sadly. Looking at the answers to the questions people asked it seems like that light probably outputs 80-100w or so. The CFL you should have 4-6 inches from the plant and the led I would start at 20 inches and lower it until you see the plant get stressed by it and then back it off a bit. How big is your grow space? You'll likely want more light later on in veg and definitely in flower unless your grow space is really small(2 square feet or so). Just an FYI you should ph your water down to 6.5 give or take a couple tenths of a point. that may be why your growth seems a bit slow though its not crazy slow.
