If I understand your post, you feed your plants with fertilizer every feeding, right? Instead of fullstrength one time, and plain water the next, you always feed a 1/2 strength mix of FoxFarm nutes?

I'm loving these nutes but definately have noticed the salt build-up issue. Can you talk about why you decided to feed 1/2 strength nutes at every feeding, rather than alternate full-strength and plain water? Thanks!
