There are some yellowing leaves on the back side lower section of the plant. The forums say to add some nuts (nutrients) to the plant again. I put some of the power bloom dry in the soil on top and then watered 1/2 gallon with 6.8 ph water. More yellowing leaves. The forum guys say to cut off the yellowing leaves. No more nuts until the 5th week of flowering. I was informed that I need to purchase a good quality ppm gauge. I added 1 gallon of 6.1 Ph water until I got a runoff from the bottom of the bag, The PPM was 980. Forum says this is good.
