The seedlings can be moved to larger pots at any time, but it will be easiest while the roots are still small and have not yet become tangled. Just be gentle when you move them and dig a larger hole than it seems they need. As to your question about the plant size without chlorophyl, right now...
You might consider watering less. Chile plants tend to prefer somewhat dry conditions. Also, very moist soil attracts fungus and algae so allowing the soil to dry out a little between waterings helps inhibit such growth.
No, geeme's assessment is accurate; the "joke" is sexist. Your response is typical of people who wish to defend their supposed right to demean others, rather than learn from a mistake.
Fataliis go from green to yellow, unless they are red fataliis, which go from green to red. Not an in-between stage. That will be determined by the genetics of the plant, not individual pods.
