Hello experts, I bought this meyer lemon tree about 1 month back and repotted it into a 14" terracotta pot. I watered it once a week when the soil is try (using a moisture meter), and made sure it was watered thoroughly. It stays indoor as we live in NYC with no balcony. However we bought a grow light and turned on during the day for extra light. No extreme heat or cold so far. However the leafs do not way upright with some wilting/drooping. Have not seen flower or bud yet. Am I doing something wrong? Does this tree look healthy? First time caring for a tree so no prior experience. Please help. Thank you!
