This week, I gave this plant a very small dose of fertilizer. I increased the distance between the lamp and the plant and set the light to about 18,000 lux. I just don't know what the humidity should be. I’m not sure if 70% humidity is suitable for the plant or not. Due to the light stress that was applied to the plant, I have to be very cautious. Unfortunately, this plant has not been able to recover from the light stress.
