While inspecting my tender tomato seedlings I happened to notice that some of the leaves are developing a slight purple tinge and curled leaves: a sure sign of a nutrient deficiency. Perhaps phosphorous. And it's no surprise really. I'm a lazy gardener and should have applied a mild dose of general purpose ferts when the first true leaves appeared. So off I went to shop around for something, preferably with a higher P and K concentration to promote early growth.
But it occurred to me that I must have something kicking around at home. I don't need much and it doesn't have to be perfect. And sure enough I had a few options available. At first I considered using a very mild application of orchid fertilizer. It had a higher level of phosphorous but also a few micro nutrients. Probably things orchids need I suppose. Then I discovered the tail end of a bottle of an organic fertilizer solutions; 1-5-5 with a touch of Magnesium. Perfect. Hopefully it does the trick.
