First of all, you need a larger container. At least a 2 gallon. Preferably 3 gallon. The plant looks to have a Nitrogen deficiency. Move it to a larger container. Check with other sources first but I do believe it looks like Nitrogen issues. Dunno what your growing medium is so.... Don`t OVER doi it with the N. But I would add a bit more if you have added any at all because the plant looks a little puny to be a month old. No offense.
