Top growth issues

You are using another account to post a question, I was trying to view your diary to see. But regardless, you chopped the living heck out of it which I'm sure stressed it out quite a bit. To make it worse, you threw it outside. As Mouse was saying; throwing a plant outdoors and exposing it to the suns UV light is like living in Arizona but then being forced to just suddenly adapt in a sauna. It's too late now, but Silica would've helped out a ton. It's not needed, nor natural, but it for sure helps marijuana plants with pests, stress, nutrient uptake, ect. I'm going to go out on a limb here and guess you are/did take a clipping from a much older plant; as the stalk looks old and hardened up quite a bit with some girth, and you threw it outside to a 12/12 cycle where as before it was inside in 18/6 under LEDS or HPS lights. Your plant is also showing slight nutrient burn, which could be tied into other stress factors as well. The good news: Marijuana is resilient as heck.
