ZOMBIE KUSH x PURPLE PUNCH / RIPPERSEEDS

Fortunately, she is healthy and continues to bloom. I have alternated watering with nutrition to avoid excessive nutrient supply in the soil. I have just flushed to check the nutrient and pH levels in the soil, the current nutrition is in the stable range of 1100 ppm before flushing and down to 800 ppm. I noticed that, if used as the manufacturer recommended dose, should be used 2 times per week alternating with water will reduce excess nutrition and save nutrition. Compared to other plants, the aroma seems less clear and strong. I don't know if the gene or smell will be strong in the last weeks. And one problem I encountered was that the upper leaf layers were curved and slightly hard. Do not know the cause because of close contact with the lamp or not?
