Amnesia XXL Auto - Dinafem - Organic

This week, watering with about 2.5L every 2 to 2.5 days. I will be lowering her PH to 6.6-6.5 The medium is full of nutrients from feeding last week and her leaves are sort of dark. Obviously getting enough nutrients and looks healthy. I probably didn't need the very small amount of Schultz drops. However, the grow beside her, Haze XXL, is sucking up all the nutrients without much darkening of leaves. It seems each plant is different for nutrient requirements.
