Watermelon auto & northern light auto

Flowering has settled in, the growth has slowed down significantly. The plants look healthy and are starting to smell a little. The northern light is looking frosty. I turned the pots 180 so the back facing side of the plant can be in front I do not feed the plants at all besides watering them with water from fish thanks. 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.
