More nutrients? Nah. I think while you may have a deficiency along the line, overall you're overfeeding...looking at the grow, you're also applying something like 15 different additives to your feed, which not only gives you a greater likelihood of overfeeding but also muddies the water figuring out where any deficiencies or overages are happening. Also I think there's some environmental issues to work on that leaf curling and canoeing suggests that there's either light or heat issues happening.
