Pale green leaves in a sprouting graft

[Axier]

I don't know if it is usual or not in citrus, but a T-bud graft of Gold Nugget on Carrizo is showing excessive pale green leaves in my opinion.
Despite this, it is growing little by little.

Now that the new leaves growing from your graft are receiving sun light and begin to transpire, enabling them to draw in more of the trees nutrients, they will darken just fine. Young leaves are a lighter shade of green than fully mature and aging leaves. The older leaves have their full complement of photosynthetic pigments and their cell wall maturity has become complete, both which contribute to the darker green tone.  For new young citrus leaves, it normally requires a month or two's time to grow into a fully  mature leaf, then they will join with their older brother leaves in the ranks of full coloration.

Thank you Millet.
Probably, the usual pale color of citrus young leaves is intensified by a not 100% joined tissues in the graft.
Hope the leaves become greener soon.

If they don't, try Keyplex 350DP.  I've tried other green up tonics, micros, with little success.  Really like the Keyplex products.  One large nursery in Florida uses such a product at a low rate of 1 qt/100 gallons.  Of course that has to be applied regularly since it's so low.

Thanks Mark for the suggestion, but I don't think that it is a micronutrient deficiency problem.
The rootstock is looped and its leaves are very healthy, with a dark green color.
In any case, if this pale color continues, I will try foliar feeding.

Just for updating, two months later, the graft is growing well with healthy leaves and nice dark green color.
Since then, It has been fertilized with "osmocote agrumes" and monthly foliar fertilization with "Bayfolan S" at 0,5 % strength.
