Last Friday i transplanted too early into a 5 gallon planter (rookie mistake)
Plants have looked fine and have grown but today I recognized that the middle of the plants are starting to turn light green. I have been trying to water 2-3 days and not over water especially in the large planters. Could this be nitrogen imbalance?
It take a lil bit for the chlorophyll to catch up to the new growth.
Looks good. 
New growth will always be a lighter shade of green. Give it a few days for chlorophyll to fill in a darker shade.
New growth will start out a little yellow because chlorophyll hasn’t processed yet. Wouldn’t worry
They guys are right. Its actually a good sign as your plant is growing fast now.
Heres a thread from another grower where the plant shows a lot of new pale growth.
