2/15 - pinned down the larger leaves
2/16 - #1 is the biggest, followed by 3, 4, then 2. Interesting to see that 1 and 3 both have 3 points on the second set while 2 and 4 have 5 points. Wonder if it's genetic or that they were smaller at first feeding...
2/17 - fed and watered, gave each about a half gallon mixed as stated above and pH adjusted to 6.5
2/19 - #1 continues to lead the pack, followed by 3, 4, and 2. With such rapid growth from the first 3, I'm guessing #2 is the only female.
2/21 - raised the lights about an inch
