Cool. Thanks man, I couldn't figure out if this was a nitrogen diff or a sulphur diff. I was kinda leaning towards a nitrogen diff because of the leaves turning yellow from the bottom up instead of the new growth turning yellow. Now back to my original question, if its a nitro diff then i need to add nitrogen. I under stand that. If its a sulphur diff then I can add a tablespoon of epsom salt. If its not a sulphur diff will it hurt the plant to add the tablespoon of salt anyway just to be sure.
