White spots on Meyer Lemon Tree

rjblea1(z10 CA)September 11, 2005

I was able to start two Meyer Lemon plants from seeds indoors and they started doing well. Recently (now several months old), they began turning yellow. Noting that this was either due to overwatering, or not enough nitrogen or iron, I now only water weekly, and feed it with Mircle Grow plant food which contains both iron and nitrogen. The leaves are now turning green again.

Suddenly, however, within the past 48 hours, I have noticed these white irregular spots on one of the newest leaves.

The spots shown in the picture are not all that uncommon. They generally occur when there is a sudden change in the soil moisture status combined with low atmospheric humidity. Unless you see an upsurge of these I do not think there is all that much to worry about. - Millet

With these type of spots the symptoms usually always appear as chlorotic areas on the leaf blade between the midrib and leaf margins that later turn gray to light brown. Following is unrelated to above) On citrus seedlings you should always water in the morning so the sun's rays can dry the soil surface before night fall, to avoid problems with Rhizoctonia, Phytophthora and Pythium fungi. Take care. - Millet

I agree with Millet. I have those spots similar to yours from time to time but I thought those were caused by some insects nibbled at the leaf and it flew afterwards. Unless there are many leaves that are like that, if I were you I won't worry about it. I always thought that there will be new leaves, new growth that will replace them. Sometimes I snip them for good looks and you know what? The plant is forced to grow new buds to replace them.
