Sucker Punch Auto Micro Hydro Grow

I feel like this week the buds didn’t increase in size like I was expecting. It seems like the tops stayed the same, the middle buds had a little growth, and the bottom buds had the most growth. Part of this may be from me looking at her multiple times a day. Three days ago I switched from a 24/0 to 18/6 lighting schedule. I’ve read that some auto’s flowering may be slowed down by 24/0 and having a dark period can help quicken bud development. We shall see. I also began adding molasses to the reservoir. Going to do a reservoir water change tomorrow as the pH is beginning swing quickly and requires additional monitoring. Please leave any tips or advice you have bud stacking and density.
