Super Lemon Haze #2 (S1 seed)

Hello to everybody, here the second week of vegetation. The aspect of the plant was very healty with an intense color of green, i decided so to do the topping in the middle of week. She growth very fast and like a pure sativa she streched a lot her truck and branches. So i tried to take her height under control with a LST technique but it was very hard mantain the same level of the the other plants. I did watering twice again in this week both with only water. 1 L + pH-down 4 drops/L pH 5.8 - ppm: 169 - EC: 0.3 ms/cm - T: 23.4°C
