Those almost mosaic leaves that look half albino are really nothing to worry about. I've had a few grow that way but the conditions were perfect and it never affected the plant.
The yellow tips, I have dealt with. In one case I was lost but I noticed that it was only the leaves getting direct air flow from the fan (wind burn). It happened again after that but it was all the fingertips at the top of the plants. In this case, the were getting slightly too much N. As it progresses, the tips claw down and become crispy. Thats an easy fix too, just ease up on the N for a few feeds.
Good luck!
