Not much to say for this week, they seemed to grow nicely. Forgot to take any pictures for the last few days of the week.
Kept the PPM at 400 for the first few days of this week then increased it to 500 for the rest of the week. Calmag was kept at a full strength dose of 1tsp/gal (200 PPM).
Since they are growing nicely I am considering topping them at around the 3rd node, will have to wait and see if they stay healthy enough.
