Wrong. Freezing will destroy buds not make them 'gross'.Cold stress can vary depending on the strain and the temperature fluctuations it went through and how often. Your plant can turn a purple color from the stress. Other problems like bud rot can appear from such hot humid days and freezing cold nights and when they freeze and thaw it can make the buds gross. Obvious signs of cold stress will include frost, stunted growth, and even death.
