Purple Punch, last round

Hello to everybody, here the fourth week of flowering. Finally the little one has reached the net, i know that i should put the net more down but unfortunately the different high of the others plants didn't allow me to do. Actually, despite the genetic suggest us that she should have changed the colour, she showed the first purple colour in the centre of the buds but not as intense. I always hoped that at least one purple punch would totally change the colour but it never happend, maybe this time?? 🙏 I did watering three times: -2 L water + pH-down 3 gocce/L (x3) pH 6.0 - ppm: 169 - EC: 0.3 ms/cm - T: 23.4°C
