Northern Lights Autoflower

Things have looked pretty good this week. Topped my two biggest plants at the beginning of the week. I am testing out a top+ train method, top+ no train method, no top+ train method, and 2 naturally growing plants. I think I got some tip burn from my light originally so I raised the light. I think one of my smaller plants got a little nute burn as the new growth was burnt at the tip and it was much smaller than my tallest plant leading me to believe it was nutrients rather than light. I flushed this plant out and hopefully everything balances itself out.
