Mimosa Gum - A foundling seed

Hello mates, we are in the sisth week of flowering, like in the ohter diaries (Amnesia e Bruce Banner) we have a problem with pH. I adjusted the pH of the water for all the plants but during this week she had more difficulties, maybe because she remained the smallest throughout the cycle. It's true that she showed some spots brown but she was still looking so beauty for my eyes, with a lot of trichomes, very dense buds and an intense smell of mimosa and gum, which gave me her name. I did watering three times in this week, the first day i used Bioenhancer (1 g/L): 2 L of water + bioEnhancer 1g/L + pH-down 6 drops/L T 22°C - 217 ppm - 0.43 ms/cm - pH 6.38 2 L of water + 3 drops/L pH-down (x2) T 22°C - 131 ppm - 0.26 ms/cm - pH 6.1
