Identification and a few questions
Hi there, I am a complete newbie to citrus. Could use some help in identifing my type of citrus. I have also included some photos of possible diseases I am having trouble identifing as well. Also should I prune the lower branches on my tree? I bought the tree less than a year ago and it was maybe a foot tall and has grown a lot since. My tree has also been dropping some of the small lemons. I'm hoping this is because it is a young tree and can't support them all yet. Any help would be appreciated! Thank you kindly, Jessica N.

I have a few pieces of advice for growing citrus in container. Even with being in a window that gets sunlight all day, unless they are old windows, this glass is designed to filter out some light. This will mean that the citrus will not be able to have enough light to produce fruit to full term. This will have to be placed outdoors when the weather is suitable, or even using a horticultural grade light for indoors. They will need about 200 watts to support the tree.
As far as spotting... This is the start of iron chlorosis. This iron deficiency can be corrected with iron sulphate. Apply this, and dolomitic lime to the soil twice per year, along with a citrus fertilizer. This will prevent deficiencies, and will keep the tree healthy enough to bear fruit.
It is very hard to determine citrus, as they each look VERY similar. You may have to wait to see fruit to know exactly what it is. My best guess is a type of lemon. Some citrus have "wings" on the stems which most lemons lack... I do not see them present so I assume that it is a type of lemon.
