i'd like to weigh in as a total noob and see if i learned anything.. don't do this but i suggest lowering everything. put the breaks on... i'd lower the light intensity, i'd lower the ph a touch(it's my understanding that young plants like it acidic and closer to 5.5) , i'd even lower the ppm's a bit( not that it's high for week two, but it's high for wounded plants) . and i would also lower the plants themselves, i'd dump out the clay and set the stem in the cup a little deeper and add the clay back in. (this is more of a preventive maintenance, my theory is the plant will use less energy trying to hold itself up and put it towards growing.) again total h2o noob and wanna see if i'm correct or not.
i would really like to hear from the experts and see what they say...
