Calm Down, Take A deep breath, she is fine! Many females that size will go off feed every winter every year like clockwork. For some the temperatures just signal to them that its breeding time and they need to take a break on food. Don't worry about it, just double check all your temperatures and the average humidity and you'll be fine.

This is quite a normal thing with females and even males during the fall/winter months. If i were you though, i might cut back the feeding to every 10-14 days since she is over 1,000 grams.

Good luck!
