>>1310411For comparison, same view on a December day. Winters are now greener than summers
>>1310417That doesn't look like a citrus plant desu
>>1310423Now we're talking
Looks like extreme chlorosis, overwatered? Too high pH? Too shady location? Give citrus full sun outside for as much of the year as possible (for my lemons it's the frost-free period, so usually March-November, very short and minor night time dips down to -2°C will be tolerated, so I even intermittently put them outside during mild periods in winter)
