Make there's plenty of phosphate, but you should also have some nitrogen and pot ash in there for good plant development. Now if we see this on our plants, they definitely need fertilizer. Yeah, your plants will tell you when they're hungry and this plant is starving. You notice the small leaves and the pale yellow color. This plant needs a boost of fertilizer.
Fluorescent tubes are the way to go.
They're a very efficient way to provide light to the plant and we want to get the tube as close as possible to the plant to get them as much light as possible, but you don't want to burn the plant. So, usually about a six to twelve inch difference between the plant and the lighting is what we're looking for and you can always tell if the lights are too close by just putting your hands over the plant. If your hand's uncomfortably warm, then so are the plants. So then we're going to lift the plants up just a little bit. All right now this is just the opposite problem.
