Zkittlez Auto Fast Buds first grow

This week was a bit bumpy, I found that I am dealing with a two main issues. First being that the plants are much too dense and close together. Makes it near impossible for me to remove the dead leaves that are falling on the Coco which eventually attract fungus. So far I have cleared the top of the medium the best I can without being able to see it. Second issue is that my timer for the irrigation is not functioning properly. I left for a weekend and my plant sitter did not realize the plants weren't being fertigated. Came back to my whole grow smelling of hay. After manually getting the feeding back on track they have fully recovered. Issues aside it's starting to look like chop day is 1 or 2 weeks away. Just in time for Christmas
