I recently got 6 kush clones from a clinic. They all were growing well but now they have started to get yellow on the edges. The center of the leaves is still mostly green and the veins are green. They growth doesnt seem to be stunted but i am worried because the yellowing is moving up the plant. I have a 400 watt hps and i use general hydroponics nutes. I think it might be a mg or zinc problem but it doesnt look to me like nute burn. please help!
