Gorilla Serious

I have done only two things in this grow. Fed them every few days and raised the lights as they grew. I did bend & tie two of the tallest stalks down at one stage when I ran out of height. Other than that I haven’t visited them much at all. So not serious. Only issue I have encountered is some rust colouration on my upper most leaves, where they get too close to the center of the lights. Happened last time to the stretchy plant. I won’t worry about it too much. But the general burnt leaf tips are a worry. Maybe too much nutes lately. I have just switched to ph 6 water only for a few days. Pretty close to flushing anyway. Pistols are 0-20% brown, but starting to change fast. Trichomes are still clear. Guessing which week I am currently in for the sake of the diary. Really I’m just watching the buds now. Looks like I have 4 plants in 4 gal soil instead of 3 similar size plants in 5 gal soil. I’m hoping to see 7-9 oz this time
