Cap Junky clone DWC

I topped off the nutrient solution daily, and adjusted the ph fluctuation, which is much more than the other plants in this grow, every other day. Generally, I noticed I was running between 5.8 and 4.9 and would have to only use a small amount of ph up to adjust the solution. The night time temperature in my area has dropped to around 30f, so my nighttime tent temps are following suit, but still well within acceptable parameters. I will say that 5 plants in a 4x4 is too many for a DWC grow. In fact, I'm not sure I would want to grow more than 2 plants in DWC in the future. Time will tell.
