Ok probably a dumb question, but wanted to try the Lucas Formula in a soil setup, but what I don't see mentioned in any material I have read is how often do you feed with this solution, is it at every watering, or every second or third watering?. I appreciate at the seedling stage it would be wise to dilute at 50%, but once well into vegetation/flowering stage do I use the solution every time I water. I suppose this question also applies to any general feeding.
