I have a potted night jasmine in the gritty mix. Some of the tips of the leaves are turning white. A few are falling off. Also some of the leaves not as green. They are looking a little pale. Dose it need chelated Iron? Thanks. filix.

I usually associate white leaf tips with high salinity levels. How about some more info, Filix?

Occurring in oldest or youngest leaves? Type of soil? Are you flushing the soil when you water? Fertilizing? with what? how often? what strength? Is your water 'softened'? How long since last repot?

Just 4 or 5 leaves have white tips. Some are turning part white, almost siver looking. this can be seen on any leaf. Old, middle, or a couple of days old. but right next to them the leaves look great. I use F.P.1/2 strenth with rain water all winter long. I got this in december. I did a repot a day later. I went from a small plastic pot, to a 3 gallon clay pot in the gritty mix. One thing I thought of is.. this plant was in a window indoors until 2 weeks ago. Now its outside in my hoophouse. It is growing gang busters even though it has this issue. Thanks. filix.

..... possibly photo-oxidation (sunburn)?
