Sensi skunk fem

Just introduced canna coco a and b nutrients I made up a ten litre bucket of water and added 40 ml each of canna coco a and b the day before so it could settle as unsure on feeding! So I’m currently feeding around 50ml to each pot as don’t wanna over feed!! Still new to the game! Worries are my tents getting to cold during the 8 hours it’s turned off! Added a little humidifier as levels are low on my humidity reader 39 ph and 25/29 degrees heat!
