I felt like I should update this in the very off chance that someone might give a shit
The fix was a simple one, Like most of you suggested I just added a little epsom ( 1/4 tsp per gallon ) and everything's back on track.
The 36w of led's are slightly out performing the 100w worth of cfl's. I unintentionally created a side by side comparison between the two while vegging in a small space. The led side is cooler, allows for more height, using less power, less frequent waterings ( I hand water ), faster more vigorous growth. The cfl will still have it's uses with seedlings and clones though..
