Welcome - There is a lot of expertise on this forum and I have no doubt you can get help with your plant. In order to facilitate that, its important to include as much information as you can...i.e. growing conditions (pot/ground, light exposure, etc), soil conditions, age of plant, irrigation schedule, fertilizer if any, yadda yadda.....and, its important to post pictures.....its much easier to help with a situation if we can get a good visual of the plant, both the whole plant and close-ups of 'problem' areas.
