My First Grow - Stealth Box

Smooth week! Expected to see more "flowering" but hoping I notice signs next week. On day 36 I top dressed with Gaia Green Power Bloom 2-8-4 @ 1.5tsp per gallon, I also defoliated and changed location of each plant. I've been defoliating but it's not doing much, it still looks like a jungle, I'm not sure if I need to go more aggressive on it or if things look ok. One day I decided to do a foliar spray of epsom salt with water and it left a residue on my leaves, I washed off the next day with a foliar spray of water only. Switched from watering can to a Chapin sprayer, it's much, much easier to get to the back plants! Highly recommend. Getting a little worried about the growth height now, after 10 days of flowering it's really stretching a lot. The plants blasted through the ScrOG net and I didn't get much time to utilize it, I mostly used it to position the tops of the colas, but next time I think I would be more aggressive with the ScrOG. Any tips or advice please let me know in the comments!
