Hi, i have a 4 months lemon seedling and i am starting to notice that the leaves are starting to get dry and brown from the tips. What is happening? Too much water? Too little? I think over-watering is more likely, since i used to water it every other day, but recently i am starting to leave like 1 week between waterings and i saw leaves were getting even worse. What is happening? I dont know what should i do. Thank you for your help.
