Lemon Wonder Auto

Hi All, This baby has become huge in the past 2 weeks. I still tried doing LST on it and as far as I can see it really worked. She became much wider and is even producing more side branches then before. The smell is great, it actually does smell like lemon. Still not using any nutrients (First time growing) to see how the plant is growing. Any tips or tricks are always welcome. Happy growing xo Nien
