Purple Punch, last round

Hello to everybody, here the fifth week of flowering. The first day of the week I did a little defoliation on the down-side part of the plant. During this week the buds swelled a lot and the colour became more intense. I did watering four times: -1 L water + pH-down 3 gocce/L pH 6.0 - ppm: 169 - EC: 0.3 ms/cm - T: 23.4°C -2 L water + pH-down 3 gocce/L (x3) pH 6.0 - ppm: 169 - EC: 0.3 ms/cm - T: 23.4°C
