They look better than my first two plants. I went overboard by putting baby plants right into Roots Organic Original amended with Baby Bu. Way too hot for the little girls. I'd be willing to bet you have the opposite problem but, a couple questions.
What soil?
Are they in two different soils?
I've never used Fox Farms products but I know that a lot of soil growers that use liquid nutes use Fox Farm Trio. I used Roots Organic Terp Teas, molasses, and dolomite lime but, I was never in a rush to add nutes to my plants.
If you decide to do the FF Trio GrowGreenMI has the Trio Quarts for only $10 more than what you have there.
