Hey just wondering how my plants are doing. ive noticed they are growing some kind of waxy cover over the stems, they are nice and thick for how long ive been growing them, dark wide leaves 3 layers of leaves for only 3 weeks of growing. Occasionally ive been soaking my potato or onion or coffee grinds in water and feeding it to my plant, since i started the water nutrient they have grown a lot but im worried im giving them too many nutrients through the vegetable/coffee infused water ive been feeding them. Just want to make sure they are healthy and happy.
