Hi bro. Your lighting seems too bright, or perhaps the lamp is positioned too close. Try lowering the lamp's intensity using the lamp's switch if it has one. Alternatively, you could try moving the lamp further away from the plant. Good luck buddy.

nutrient imbalances, probably some bad watering habits, and ignoring a progressing problem for several weeks. maybe you used some sort of useless foliar spray, too? insufficient information provided to give more detailed respone
