Wedding Cake, Barney's Farm, Feminized

Day 1 A new week has started again. Added 6 l of fresh water and gently m/g/b, calmag and a little bit of Bloombastic. EC 1.7 and pH 6.3. Day 3 She drinks! Added 11 litres of water and the reservoir did not even get full. Also added micro 20 ml, grow 10 ml, bloom 25 ml. EC 1.8, pH 6.1 and reservoir water 21°C. Later the pH was at 6.0, so 5 ml of silicate added. pH 6.3 EC 1.8. Day 4 pH keeps on dropping down. More silicate (10 ml) and a couple of litres of water. EC 1.8, pH 6.2. Day 5 Had to remove some of the biggest leaves for lower buds light intake and better airflow of course. I totally could have defoliated more, but I always go too easy with the plant because I am too scared. Added some fresh water and just 2 ml of bloombastic. EC 1.8 & pH 6.2. Everything looks ok.
