blotchyness

One of my girls (i hope) has developed patches of discoloration on its leaves. The other ones have good color at this stage in the same environment, however this one is from a feminized seed (chocoalate chunk) while the others are ones i have collected along the way. The discoloration is a very light green that surounds the veins on the fan leaves, both the main vein lengthwise and the small ones going to the edge of the blades. there is still some normal color between veins but the discoloration spots these areas too. There is no yellow or brown and does not look like nute burn as i have experienced before. It is in soil that has a veg blend of nutes but at fairly low levels. 1 and half weeks old and the discoloration started once the first real leaves formed and has continued at each node since. Doesnt look like any of the probs i have seen in other posts so far. Any ideas? Maybe just a genetic disorder from the feminizing process?
