Mid veg? I would assume a plant in mid veg would be at least 4-5 weeks old and well a tad bigger than this. That is a ridiculously high PPM read im surprised they are not showing signs of over fertilization I like to set the ec of a plant of this size to around 1.0 ec I dont use ppm but tht ppm value would have your ec at around 4.4 which is well way way way too much its like over 2.5x what she needs has she been growing slow ? I can only assume so, I would flush her with just ph balanced water until she recovers and starts throwing out fresh new healthy growth. best of luck anyway pal I see you have been quite heavy with defoliation too. This will slow her down even more keeping in mind and add more stress on to what shee already going through lol Best of luck anyway im sure she will bounce back with a good flush.
