Help!!! alas my tree has lost most of its leaves..The few remaining are shriveled up and dry. I wasn't too worried because I knew due to the planting stress it would lose some. But now almost all of the leaves are gone and a few tips of the branches are turning brown. IF anyone has any suggestions please help..Here is some background.

Got the tree about 4 weeks ago and planted it in a mixture of miracle grow and sand. It is in a 24" pot with some hardwood bark chips on the bottom for better drainage " I read somewhere to use coco shells but couldn't find any this time of year and I use the bark chips in my banana pots also". It is in a heated building at 72degrees under a 400 Watt 10,00k MH bulb with a t-5 unit (6 bulbs at 6500K grow bubls) The tree is within 3ft of all the bulbs and recently I just put the pot on 2" of hard styrofoam to get it off the ground and also added a large Seed heat mat under it. All the plants in the building are misted daily with a 5 gal pump sprayer just until wet and this also keeps the humidity in the shed around 60%. I have been watering once a week and making sure it is not getting too much (same as for my banana's) and everything else in the shed is doing great. Today I uprooted the tree added more sand (close to 30% now) and also added a "Citrus Fertilizer" to the soil. I also added a more bark chips to aid in drainage. I ordered a pH and moisture meter but it hasn't come yet. By the way the lights are on about 10hours a day and the tree also gets supplemental lighting from a south facing window. Also the plants are not getting "warm dry air" from the heater blowing on them it is blocked from hitting the plants directly. So any suggestions? I know most here are good with banana's but I have no problem with them as they are close to 9" indoors now and growing well.
