I decided to use Tps & Foxfarm together to remove the heavy salt build up in the soil. I noticed that by using Dr Earth Fertilizer, my soil ppm is alway super high. reusing soil with high ppm seem to stunt some of my plants growth.This is the second week of desalting the soil. I also put all four of B.K. in the tent with Blueberry Kush and both Gorilla Cookies #1 & #2. So currently there are seven plants in a 3x3.
