What is most likely the problem if a plant cant support its own weight?

If a plant can't support its own weight, it is likely experiencing issues such as insufficient light, leading to weak, leggy growth, or inadequate nutrient supply, particularly nitrogen, which can affect overall strength and vigor. Additionally, overwatering or root rot can weaken the root system, making it unable to anchor the plant properly. Pests or diseases can also compromise structural integrity, causing the plant to collapse under its own weight.
