So about 2 weeks ago I accidentally read a feed chart wrong and gave my 2-week old girls a double-strength dose of 11-40-13 seedling booster. 2 days later I realized what I had done as the plants showed some slight chlorosis. I watered them and took a ppm measurement and had readings as high as 1,600. So I flushed them until I got readings in the 300-320 range. The plants keep showing chlorosis. They have grown 3-4 inches and the new growth always looks normal green, but as the leaves get bigger they start to show chlorosis. So when they dried out I watered them and took EC measurements. I measured the tap water and it read 0.7. I am getting runoff EC readings as high as 1.6. Do you think that the higher readings are residual from the over-feeding, or do I have a salt build-up and need to flush again? My tap water is pretty consistent at 180-195 ppm. Temps vary from 75-78, and the humidity is 63%. I have not fed them since the flush because the EC was still high. Is this a lockout or nute burn? I gave them a treatment with Foop mist, but they look no different. Should I flush them again, because they have dried out and do need watering?
