Sensi Skunk Automatic - First Ever Grow

Had an absolute nightmare this week. The upstairs power in my university house blew out so had to run an extension upstairs but could only have the lights on for about 8-10 hours as I had to hide the box in my friend's room as the fuse box was in the wardrobe where I was keeping it! Probably stunted growing a bit and confused the plants with odd light schedules but oh well. Bought a small ultrasonic humidifier in the hope it would increase the humidity of the box but my thermometer only reckons its gone up by about 5% even though it is on all day. Starting to think about training the plants as I don't want them getting massive and also want as many colas as possible. Started to properly water the plants now gave them about 500ml of mixed Bio-Grow fertilizer about every 2 or 3 days mainly judging it based on how damp the top of the soil it. Probably could do with another light as the plants lean towards the centre, however, I've just been turning the pots every now and then to get some even growth.
