bigger container, 5-1-1 soil mix 5-1-3 feed

I would be checking the roots to see their condition after being over watered. If you are using Foliage Pro, your leaves shouldn't look like that. There are no trace minerals in Foliage Pro. I use Osmocote Plus to supplement my fertilizer and so do many others. I love using fish emulsion once a month because it is high in nitrogen and turns my leaves a very healthy green. You may consider using it. What type of soil is your tree in?

It’s in Kellogg’s citrus/cactus mix. I’m too lazy to mix my own 5-1-1 and these were growing really well last year.
