Super Lemon Haze #2 (S1 seed)

Hello to everybody, here the fifth week of flowering. The yellowing doesn't stop and now I think the problem is still the same, the fungus. I got the sickest leaves but could not cut them all. I didn't nebulize anything like i done before because the plants is almost at the final phase. This week i find the branch with the bigger bud lying on top of the other plant without breaks, so i fix the heaviest branches. During this week the buds exploded, they become very big and dense. The smell is more punget now but still fruity. She isn't sure the most beautiful plant but continue to give me a lot of satisfaction. I did watering three times: -2 L water + pH-down 3 drops/L (x3) pH 6.0 - ppm: 169 - EC: 0.3 ms/cm - T: 21°C
