Watermelon auto & northern light auto

They are growing like they are in veg. Still getting new growth. Bud sites are more and more defined from top to bottom. Not sure how big they will get but I'm guessing not much more. 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.
