First Time Grow! - White Widow Max Auto

Last week I mentioned, I noticed that some of the plant's leaves from the Main COLAs are turning yellow. I am trying to correct the problem if there is one, but I am not going to over-correct. It is possible that it is due to my plant is also getting near harvest, since this strain says it can be harvested as early as day 70-75 from seed. I am trying to go for a total of 84 days before harvest, but I will harvest earlier if need be. I noticed 1 main COLA and a few side COLAs were starting to get too heavy for the branches, so I decided to use the net as support from this point forward. Positioning the heavy COLA's made it to where I had to defoliate more of the plant for airflow. OOPS. I accidentally snipped one of the side COLA's. Its whatever though. There are about 8 main COLA's on this plant, and at least 10 more side COLA's comparable to what I snipped. I will dry it, and see if it is salvageable. My plant has a ton of resin now. When I handled the plant to get it positioned within the net, my hands got so incredibly sticky. I used apple cider vinegar to wash my hands.
