beginner, g13 blue cindy

hello to you reading this, so this week allowed me to fire a bit of money into the room so i got hold of a exhale co2 bag and a humidifier which seems to have helped and made a bigger difference than i had expected. i also got some npk raw yucca that i started using yesterday so is a bit to early to notice anything. iv still been tying down the main branches and making it get bushy before it shoots up, at least thats my plan. i fimmed a few of the bigger stems and i gave them a good spray with a 10ml/l calmag solution at the beginning of the week and some foliar at the end. any thoughts please say, i am also aware the photos are terrible but i was rushed and they are mainly for comparison.
