Ok reversed Version of my Answer. Yes 1800 ppm is pretty high for that young girl,half of the ppm is enough. but as i dont know wich fertiliser you have been using its critical to say something. If you use organic fertiliser the parts have a bigger desity. I can only say something to your EC is you use sythetic nutes. But as you flushed that wont hurt at all. Bat guano and wormcastings are better given in flowering Stage
