I'm hooked now

Hello again, It's been another great week and they are growing really quickly. The photos I have taken are been taken every day so you can truly see the progress they are making. The HPS has been upped to 400w and will stay on that for the next couple of weeks. I have had to move the plants to their final pots due to the growth spurt and roots are coming out of the bottom. I have upped the feed slightly, but still slightly below the recommended dose. I will give them the recommended dose in a week's time. If they carry on with the rate of growth I'm seeing now, I will be switching to 12/12 in 3 weeks time. LST will be started on Sunday, as I wanted the plants to get more established but still flexible enough.
