Day 11 - Start of week 2. Things are looking good so far. #3 is the runt (pun intended) and #2 is showing a slight deformity, but otherwise no issues.
Day 13 - Watered them today. Water PH was 6.6 for 1 and 2 and 6.8 for 3 and 4. PPM was 75 + 156 for the water's initial PPM. I will list the nutrients I am using, but listing the amount of each nutrient used is difficult because I make solutions for veg and for bloom and then add them to get a PPM that slowly increases. This just makes it very hard to say exactly how much of anything is going in per feed.
@greeneric, It's from AC Infinity. You can get it with or without the lights and I had no problems with it at all. It also has a extension piece in case you want to do clones in there. Worked perfectly with the rapid rooters. I've only planted 7 seeds, but I'm 7 for 7 with germination and all of them were simply planted in the rapid rooters with water.
