Hey bro! π It looks like the plant is generally unwell. The leaves are thin, there's discoloration and necrosis. A lack of cal/mag in the watering is causing overall malaise, and a deficiency of nitrogen (N) prevents the plant from fully converting chlorophyll. Your symptoms could also be due to insufficient lighting in the growing area. Measure the light intensity with a lux meter around the plant; if the readings are below 2000 lux, then increase the power of the lamp or lower it closer to the plant, aiming for between 2000 lux and 20000 lux for its age! πππ Good luck, bro! π
