hey bcsquatter,
there's a way to grow where you won't experience this kind of problem. there's a way you can prevent this kind of thing from happening and you'll take all the guesswork out of growing. the method is this - don't try to do anything special. just get some Foxfarm Fruit and Flower powdered fert at your grow store and put two cups of it in a five gallon container of potting soil and mix well, then put your plants in that and just water them when their thirsty. That will solve 99% percent of your feeding issues.
