White spots on Meyer Lemon Tree
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.
