Chicken Manure in Coco (First Grow)

Everything going well so far. Internodal spacing is really low which is giving me some worries. However plants seem healthy and due to this I also got 6 nodes going from the big plant and 4 with the smaller plant with just one topping. The little guy has been moved to the balcony.
