Tiny, much appreciation for your post. I've enjoyed reading and learning from your own grow logs :-)
The spacing is certainly an issue, and one of those valuable learning experiences I plan to put towards my second grow. I was thinking of removing one single plant bucket and adding another double plant bucket. So instead of the 1x1x1x1x2 setup I am currently running, I want to switch to a 1x1x2x2. I may even go with a three bucket (2x2x2) setup. In your experience, will 2 plants per 5 gallon bucket cause any obvious problems?
Thanks for the tip on painting the bucket, I will buy some spray paint designed for plastic and take care of that on Saturday my first res change out.
As for the clear tubing, yeah, I ran out of my black tubing so I used my spare clear tubing for two of the buckets X_X I plan to switch that out on Saturday as well.

My dark cycle runs from 12:00am â?? 6:00am. I checked on my babies this morning at 6:30am, day 3. Their pH was, surprisingly, perfect. All of the plants were sitting at 5-9 =- 6.1. The water was resting 23/24c. Hereâ??s how they look:
