Radianceanswered grow question 5 years ago If your plant is an Indica dominant, the color should be much darker. Dark green. Could be nutrient deficiency, probably nitrogen. did you already feed them nutrients ? Leaves turn yellow and die off when the plant is missing nutrients, it shouldn't happen at your stage since the plant is so small... Anyway I don't see a big problem now, you should keep monitoring daily and see if more leaves turn yellow. If it's a sativa it's normal that that the plant is a lighter green
