Amnesia - Ganja Farmer growth test

Hello mates, we are inside the sixth week of flowering. The first thing that i have to say is that the pH of the solution has changed probably due to the change of the temperatures in the house so i fix the amount of Bio-pH- to reach a lower pH. The #2 is going on very well differently by the #1 she wasn't hit with the same timing so i was able to change the pH in time without visible signs on the pant. The buds are swelling so much with a great amount of trichomes and the smels now is so intense, the first taste that i feel is a mix of pungent and sweet. The #1 has her problems without surrender, during this week her health first worsen then at the end of the week i see a good recovery. Anyway during this week she grow slower than the #2, the smell is immature yet but not so different to #2. The first day i gave her a different solution with a lower pH: 2 L of water + bioEnhancer 1g/L + pH-down 9 drops/L T 22°C - 217 ppm - 0.43 ms/cm - pH 6.13 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
