When To Start Flowering
You should only start flowering flowering your weed plant only if you have completed all the training you desire your plant to experience for this grow. Once flowering begins the stems and branches stiffen up and are much harder to manipulate without breaking. Just make sure not to over do any training during the flowering phase.
What Triggers Flowering?
Changing the light cycle to 12 hours on and 12 hours off will indicate to the plants that it is time to begin flowering.
Think of the light cycles in nature and when our plants would be growing. In the spring and early summer we have very long days filled with sunlight all day long. By the end of summer it gets darker much earlier and this is the indicator in nature that winter is on it’s way and they try to reproduce by creating flowers before dying.
Change Over To Flower Period Nutrients
Make sure to start using the nutrients designed for the flowering period and stop using the ones meant for the vegetative state. Flowering your weed plant will cause a change in growth behavior which requires a change in nutrients to support the new growth schedule.
Stretching
One of the first stages of flowering is called the stretching phase. For indica’s this stretching your plant will most likely double in size from when it starts to flower. After the stretching is complete your plant will stop growing taller and focus all its energy on reproducing, which it does by creating some nice buds.
