Super Lemon Haze #2 (S1 seed)

Hello to everybody, here the fourth week of flowering. The plant continue to get bigger and bigger :) the smell is so fruity and tropical, different from the original Lemon but so intresting. The buds are the tipicals of a sativa strain in fact they are pointed and tend to grow vertically rather than swelling. The yellowing of the lower leaves afraid me so i decided to feed again with BioBloom (1g/L of substrate) and then with BioEnhancer (1g/L) to help her with nutrients and the fungus. I did watering four times, the first with BioEnhancher: - 2 L water+ bioEnhancer 1g/L + 8 drops/L pH-down (x1) pH: 6.2 - ppm: 230 - EC: 0.46 ms/cm - T: 23.4°C -1 L water + pH-down 3 gocce/L (x3) pH 6.0 - ppm: 169 - EC: 0.3 ms/cm - T: 23.4°C
