This is the week of testing it appears. As this is my first grow, I tested 3 different methods of training; LST, Topping, and leaving one alone. This was done 1 day before this update was posted. Approximately 4 days ago, I noticed a Nitrogen deficiency had formed overnight via the undergrowth (yellowing leaves, slightly curled). This gave me the signal that it was time to transplant since it has been approximately 3 weeks since germination. Because it has been 3 weeks, I am assuming my Happy Frog soil was most likely flushed of nutrients. I transplanted all 3 girls to 3gal fabric pots and gave a light watering to each to get the nutrients flowing and soil settled. The yellowing of the undergrowth has stopped spreading, however, it does not seem to be going away. We'll keep an eye on them, they probably will never return to full life.
