New growth very light green

Hey guy's i have a couple blue dream plant's about four feet tall been feeding ff grow big for about a month now and was just wondering if the light green is normal or am i missing something?

It's probably starting to convert to flowering. The new growth will look lighter green for whatever reason if that's the case.

Need pics, but could be the beginning of a nitrogen deficiency. If you're going into flower make sure to continue feeding with a N supplement for the first two weeks.
