Hey, bro! :wave: Judging by the photo, you have an excess of nitrogen, reduce the "grow" supplement by three times. Due to the nitrogen excess (bright green color of the adult leaves with a glossy shine), you have developed a phosphorus deficiency (spots on the edges of the leaves). Lower the nitrogen, bro! Phosphorus is hard to access for the plant because of this. Good luck, bro! :ok_hand::innocent::+1:
