I got these two kumquat plants last spring and have been taking care of them like they're my children. I follow most of the advice I found online : Water them when 2-4 inches of the top soil is dry, use a citrus fertilizer once every 2 weeks, I have them in a south facing window with grow lights and spray them with a water bottle once a day. Recently I was away for a week and before I left I made sure I watered them well until it poured out the bottom. Since I was away I couldn't turn on the grow lights but I figured this wouldn't be such a big deal since I'd only be gone for 7 days. When I came back the Meiwa had lost most of it's leaves and the Nagami had lost a good portion of them. I noticed the soil was drier than usual which is strange because I usually water them once a week. We noticed most of our other plants also had brown leaves which again is strange because they hadn't gone without water more then they usually do. Our hygrometer was reading 30% so I suspect that the air might have gotten really dry since no one was living there for a week? Also since I wasn't there to turn them on and off they didn't have the grow lights on for the whole time. Anyway I've been taking extra care of the kumquats since I've been back but the leaves that were still green are still turning brown and falling. At this point the Meiwa is practically bare but the Nagami seems to be doing better although it has been dropping fruit. I suspect most people will tell me to cut the fruit off to give it a fighting chance but I'd like to avoid that if possible seeing as I've been waiting almost a year to finally harvest them. What am I doing wrong ? Is it still getting over the shock of not getting the grow lights and being underwatered? Is there anything I can do to help them recover other than cutting the fruit off?
