Meyer lemon tree leaves turning yellow
Hi all-I have a Meyer Lemon tree which experienced tons of new growth over the winter, after I wrapped the base in christmas lights per the advice I recieved on this forum. Anyways, Many of the new leaves are turning yellow, mostly starting from the tips of the leaves, but some have yellowish splotches covering the whole leaf. This seems to be affecting almost all the new leaves, but not the older leaves. The pot has good drainage, and sits on a large tray of pebbles, and I water about once a week(indoors). I have been feeding it monthly with miracle grow all purpose fertilizer. I can see no insects on the leaves, but there is some webbing on some of the branches. Some of the leaves have small dark circular marks on the underside of the leaf, but not all. I was hoping for some rich green leaves, and these seem pretty anemic. I don't want the tree to be harmed in any way, anty assistance would be appreciated.
