strange leaf discoloration

ive noticed some very slight leaf discoloration around the bottom leafs of my plant, its 24 days old and vegging. Ive only noticed it on the 2 bottom leaves and its only on the tips of the leaf. Its very slight yellowy areas with what looks to be brown dots on it. I can try to take a picture but i doubt it would be able to capture it. Does anyone know what this is? I added nutes to the plant twice in one week, could it be nute burn? I dont think its lamp burn becuase its on the 2 leaves the get the least amount of light and there the furtherest distance from the lamp (250w hps.) Over/under watering?
Any help would be much apprectiated.

could be lots of stuff. I had that problem and what it ended up being was that i had splashed some nutes on the leaves while watering and that cause it. its hard to tell with out seeing. could be nute burn or bugs also. inspect for bugs (some are really really tiny) and get back to us. if it spreads upward to other leaf sets let us know too...nute burn starts from the bottom up.
