Welcome to the Bedroom Garden

Here we go! Week 2. It seems like the lady is really enjoying her spacious pot; However, judging by the rate of nodal development it would seem there is more growth occurring below the coir surface than above. This is probably assisted by plain water feedings. I've heard that the plants can go weeks from seed on nothing but tap water, but I won't be pushing this. It id probably time time to start adapting the seedling to the water soluble nutrients. By the way, it would seem my seedling is beginning to shed her skin. Sort of like the Incredible Hulk tearing his shirt. Is this a normal part of profound stem growth, or am I looking at rot issues? I really believe the former, but maybe she's 1/2 dead already ? :'D
