Amnesia - Ganja Farmer growth test

Hello mates, we are inside the fifth week of flowering. After two days the amnesia #1 started to show some little spots light brown, this condition was gone badder during the week. So i decided to feed again with the Bioenhancer the last day of the week and only that day i saw that the pH of the solution with the Bioenhancer was too high so i changed the amount of pH-down. Infact the last day, indeed to give her the same watering schedule of the #2, i gave this: 1 L Acqua+ BioEnhancer 1g/L + 9 gocce pH-down T 22°C - 217 ppm - 0.43 ms/cm - pH 6.13 For this reason the flowers of the #1 are a bit more little than the #2 and the same goes for trichomes about the amount. I hope to fix the situation in time to the harvest. I did watering four times in this week for the Amnesia #2, the first day i used Bioenhancer (1 g/L): 2 L of water + bioEnhancer 1g/L + pH-down 5 drops/L T 22°C - 217 ppm - 0.43 ms/cm - pH 6.5 2 L of water + 2 drops/L pH-down (x3) T 22°C - 131 ppm - 0.26 ms/cm - pH 6.3
