U need to buy some better food, not sure if that's the cause. Half the leaf turning all yellow like that is pretty crazy. Look into Floranova. They have a 1-part nutrient that works great.
1 bottle for veg and 1 bottle for bloom. It's easy and you get great results
I'm with MrBee, I think it's genetic, like variegation. I see absolutely nothing else wrong with that plant, nothing at all. Can you get full plant pix?

I would just chop that top off and burn it saying some kind of chant. Miracle grow works fine for veg if you have some kind of Ca and Mg sup. Flower ehhh.
