Feeding everyday is not right , prefer to feed every 2 watering ( one with water , one with nutrients )
3L a day is too much , prefer to settle a dry wet cycle so wat until the pot is dry ( not totally ) , then lift the pot and remmeber the weight , then water the pot , lift it and rememeber the weight , the best time to water is now when the pot will get back to the light weight.
