Just watch next few days, if those leaves stay light and the veins keep getting darker you may have beginning of magnesium deficiency. New growth is lighter as @Brandon said so watch a couple days before changing anything.
Yes it is getting lighter. Does anyone know what my run off phone should be in soil? Its like at 6.3
@hpsgrower 6.3 is good in soil. What week are you in, what are you feeding and how much? Are you using cal-mag? You just transplanted, did the root ball break apart? Can you get a run off ppm?
Looks good to me new growth is normal lighter
