I feed all the citrus same times and all are green & healthy & leafing out... fruits on many, but what's wrong with buddha? I almost lost it last winter & had to cut dead branches down & then trunk to above the graft. Looked like a dead stick. 2 branches grew & now it's this! The upper leaves look OK except a little curled, but bottom leaves are deformed w/ yellow blotches. Thanks much

Patty my Limequat is sort of looking like this, hope someone knows!

Your newer growth looks good. It is your older growth that has the yellow coloration and the burnt leaf tips and margins. I would say the problem was at one time high soluble salts. However, it looks like the tree is no longer bothered by a toxic level of soluble salts. Did you flush you container? Cntainers should be flushed at least a couple times a year. - Millet

Yes, I did flush it twice this yr so far. Since the first flushing, it started to come back greener but still is not as good as the rest of citrus.
Thanks Millet, do you treat your buddha any different than your citrus? Diff ferts/soil?
