Watermelon auto & northern light auto

Have some deficiencies or ph imbalance still troubleshooting. The pH was off but now everything is back on track. I have some amber on the watermelon, the northern light is milky from top to bottom but no amber yet The smell is pretty strong I do not feed the plants at all besides watering them with water from fish tanks. Made some live soil and added horse manure, homemade bone meal from fish bones, compost from vegetable scraps and black soldier fly frass. I do not use chemicals on any of my grows.
