shouldn't need food at that size..GOOD Soil will give it all it needs. Check your Ph, always a good starting point then really check the soil below the half way point. I had one that started out the gate running, then out of 7 was the only one whose leaves wilted and after alot of reading I decided to transplant and found the bottom portion was soggy to the point I could squeeze h2o out.I'd used clay balls and guess they blocked the drainage holes. She is gorgeous now and I watch all their soil for excess wt. and moisture.
