Most all plants will go thru a stretch during the first few weeks of 12/12, regardless.
-This is from the plant getting less light.

If putting an immature plant in 12/12, it will stretch just the same.
-Difference is, this plant will continue to 'veg' in 12/12 until it becomes mature.

In most cases, mature plants are indicated by alternating nodes and preflowers.
