Thanks for the reply man. You'd be proud - I'm slowly building up a nice grow space. My extractor fan arrived today and I expect the budbox to come soon Eventually, I'll get a cool tube and I'll be set up Here's a few pics of the kids in the wardrobe before their new luxury home is set up. You can see the yellowing of the leaves. I read that added nitrogen will take a week to show its effects but all seems healthy otherwise.
