Purple Punch, last round

Hello to everybody, here the sixth week of flowering. During the past week i noticed that the pH's solution was a bit low. So i started this week rising up the pH's solution until to 6.5, i did this because i noticed that the buds didn't swell how i expected. I'm very satisfied about the plant and her journey until now but i always want to reach the better result, the next growth cycle i'll try to maintain a better pH of the solution during all the cycle. All the buds have a great aspect and an incredible odor, in particular the bud with the fasciation. Unfortunately also this time the plant don't change totally the colour but in the innermost part the buds have the purple colour. I did watering four times, the first of the week with BioEnhancer: - 2 L water + bioEnhancer 1g/L + pH-down 5 drops/L pH 6.5 - ppm: 206- EC: 0.4 ms/cm - T: 21°C -2 L water + pH-down 2 drops/L (x3) pH 6.5 - ppm: 169 - EC: 0.3 ms/cm - T: 21°C
