Here's how I'm looking at your plants.

I use synthetic fertilizer, ro water. At that stage, early flower. I'd be running 700-750ppm. With 700 being the target. I wouldn't go past 800.

When I read 1500ppm. Given the problem of the plant. The PPM is way-way too high. 1500 is twice the dose. Plus its expensive.
