Hi was just wondering if I should be worried part of the plant has brownish looking buds growing. Some are nice green and healthy looking but about 1/4 of the plants buds are a very noticeable different color. Fairly brown and dark looking compared to the rest of the plant. Does anyone know if there is or isn't a problem and if there is what could be causing it. I have attached some photos. If anyone has any ideas about this please let me know.
