Emilia the Banana Blaze

Not a very good week for poor little Emilia. First I noticed her baby leaves turn yellow. Didn't think too much about it but then her first node leaves started turning yellow as well. It seemed the yellowing was "climbing" up. So I looked even closer and realized that while she was 5 nodes tall and working on the 6th, none of the growth tips had grown. At all. Even at the first node they were still only a couple of millimeters. Usually at this point they're at least a couple of inches! Got some advice from experienced growers on an internet forum and was told she was hungry - she needed nutes. With all my previous grows FoxFarm soil was enough for at least a month into veg but I guess Emilia was hungrier than most. I immediately started feeding her. Let's hope that was it and she'll recover soon.
