I haven't found any real difference in taste. However, the pink color is unique. Here are some pictures from last month of my varigated pink lemon: Hope these help and also given the warn weather we have been having, the bush/tree is covered in new purple growth and soon to be flowers....It is also probably another 4-6" larger. Loves the heat! Peter

It could, of course; salt is salt; with "moderately hard" water, if just takes a bit longer. Adding a bit of vinegar beforehand; and allowing it to settle, a lot of the salts would be precipitated out. Do you know the pH of your water? I would presume it to be high, which would worsen your problem and help produce some of the "look" of your plant.

I am a bit nervous of the condition of my tree once it arrives. It shipped out 10/3/17 and will arrive 10/10/17, 7-8 days in a dark box sounds like that poor trees going to be in rough shape. What is the longest anyone's trees have been in transit for?

I'm going to try and stay general. Pots shouldn't be left on floor if it can be helped, coldest spot in room - leading to cold roots. Are you attempting a holding action or want winter growth. You give no temperature numbers and no pictures. Do you use lights? Leaves should be well lit but not necessarily hot, or you'll get leaf drop. Air temperatures for indoor growing should be in a 72 to 85 degree tops range indoors, your soil temperature should be above 70 at all times. there should NOT be a huge differential but there generally is some. You need a thermometer for air and soil. You won't be watering as often indoors as outdoors in wind and sun, possibly only once a week in winter but pot should be flooded when you water to get lower pot moist - encourage root growth and flush out any fertilizer salts. Soil i supposed to hold moisture for a while and then dry out from the top down - just like the garden. You need to test - I use cheap wood BBQ skewers and poke in the soil all the way down to bottom to watch for wetness depth. Small pots dry out quicker than big ones. lots of variables. You can shine a cheap clip on spot light on roots/top of pot to warm them so they can supply needed water to leaves if needed. Some people here successfully keep their trees in a very cool state - probably in the 50 degree range (I'm not one of them - someone will chime in), without too much light, and not too much differential between air and soil temps as a holding action - little to no growth and hopefully no leaf drop .
