Hi, my Bearss lime has been in the ground for 4-6 weeks. About two weeks ago it began to change color. I know this has been discussed somewhere on this board, but I haven't been able to find it again. Anyway, here are a few photos of my yellowing leaves. It seems to be happening to both the new growth and the older leaves. Please help, I don't want this guy to suffer. Thanks.

Manganese Deficiency
Deficiency appears as dark green bands along the midrib and main veins surrounded by light green interveinal areas giving a mottled appearance (Fig. 7). As severity increases, the light green interveinal areas give way to a yellow-bronze coloration. Both manganese and zinc deficiencies may occur on calcareous soil and may be more severe on trees with highly pH-sensitive rootstocks. Incipient manganese symptoms may sometimes disappear as the season progresses, so leaves should be observed several times before remedial action is taken. Soil and foliar applications may be effective in correction of manganese deficiency.

Zinc Deficiency
Early stages appear as small blotches of yellow between green veins on the leaf. With severe deficiency, leaves may become increasingly yellow except for the green veinal areas (Fig. . Under severe deficiency conditions, leaves will also be small with narrow pointed tips on terminal growth. Foliar fertilizer applications are usually recommended for correcting zinc deficiency. Trees with citrus blight will also show leaf symptoms of zinc deficiency.

Thanks David, it looks like a manganese deficiency to me. The link you sent was just the kind of info I've been looking for. I've got it bookmarked but I'm hoping I won't need to use it much.

The light green/dark green boundary shows the characteristic shape of magnesium deficiency.
