First try Kannabia seeds - Colombian Jack

Hello mates, welcome inside Colombian Jack's first week of flowering. I did some changes in my environment: i placed the net for ScrOG method at 30-35cm from the pot; I changed the light schedule raising at 80% the power of both LEDs and setting at 45 cm from the net; I fed all the plants in the tent with top-dressing thecnique, i gave to Colombian Jack 60 g of BioBloom of Green House Feeding; I put in the tent the dehumidifer; I changed the ratio in the Base water raising the amount of tap water so 3:2 ratio (demin:tap water) because i saw that some had the first signs of need, others more serious. During this week Colombian was the one of them that sufferd a lot for Ca defiency, compared to the other plants in the tent she was the smallest. In fact she didn't stretch as i expected but she has increased slowly her crown. I did also LST with defoliation and pruning trying to stimulate her vertical growth but at the end of the week she was still struggling. I didn't a big pruning for her because she wasn't so healthy so i was light 😅. We will see the next week if Colombian might recover.
