Glue Gelato Auto BARNEYS FARM

so this week my fan decided to fall off its mounting and land straight in my plant. ripping off a branch... devastated. still growing nicely just hope it didn't shock it to much. saying that also flushed the plant as the soil was hot in nitrogen. leaves had gone dark and the tips were clawing. i checked the run off and was like 9000 ppm. now I'm a newbie and not sure if u measure runoff different with soil but that is crazy numbers...like plant killing numbers but they still growing just with some nitrogen toxicity. flushed them down so now got a clean slate and will start bringing in bloom nutes slowly over next few days. also purchased a mars hydro tsw2000 today so that will be going in once it arrives. will have 300w instead of 150w so hoping for denser buds
