Greetings! This haunted me during my last grow. I thought it was from a slight fruit fly larvae problem I had earlier on in the previous grow, and everything finished, so I 'thought' it was a thing of the past. Strain: Master Kush This time, I'm into my 2nd week of flower, plants look GREAT except for the yellowing that I don't want to spread. Thick, green, etc. They are in 7 gallon pots with roots organic 707 soil. I have raised them from clones I took myself. Vegged for approx 10 weeks. They are scrogged individually. Using Cutting Edge solutions nutrients. I am using their main 6 ingredients at recommended levels. Today, I watered 1 plant with house and graden A+B mix just to see if it stops the yellowing. My gut tells me this is nutrient related. I know in the pictures below, it doesn't look like much, but I fear it's going to spread. It was pretty widespread before. Although the plants finished, they took 10 weeks, and I still did not have as many amber trichs as I had wanted. Thoughts? Thanks in advance bros.
