I'm about here in my grow. Glad to see yours are bright yellow green new growth too. That had me worried. I avoided topping because everyone says no topping bad, but I accidently "topped" one of the plants in my grow, and it did fine. I have a Gorilla Glue in the same grow that I topped, it had a quad underneath it.
I've realized you can kill some plants following everyone's advice.
I saw on another post where they used gradual defoliation, another autoflower no no, with good success.
I didn't like Happy Frog either. I'm using Biobuzz Light, its a little cheaper than promix.
