I count flowering from the day you start 12/12 lighting.

When to Flower
Indoors, growers force marijuana to flower at any time. Even seedlings will indicate sex and produce flowers given the right conditions. Marijuana flowers in response to the light cycle. Under natural conditions, the plant senses oncoming autumn by chemically measuring the uninterrupted dark period. Indoors, when the light regimen includes a dark period of 10-12 hours each day, the plant stops its vegetative growth cycle and starts growing reproductive organs, male and female flowers, which usually occur on separate plants.
Here are the stages of flower growth.
1. Slowdown then stop of vegetative growth. 4-10 days after beginning forcing. Lasts up to a week.
2. Appearance of first flowers. 10 days to 15 days after beginning forcing.
3. Massive growth of flowers at the budding sites. Continuing after the first appearance of flowers for 30 to 40 days. During this time the buds develop
and take shape. Starting with a few flowers, layer after layer of flowers is grown until the bud sites are merged together into one large cola.
4. Maturation. Eventually the pistils start to turn color from pale white to red or brown At the same time the flowers close up, forming false seed pods. The small glands on the flowers now start to grow. These are called stalked capitate glands and are composed of a tiny stalk supporting a thin clear membrane. As THC is produced near the site, the membrane swells with the potent liquid. The membrane stretches and the gland takes on the appearance of a mushroom. When the glands have swelled and the pistil has receded into the false pod, the bud is ready to pick.
how old are they again ??? BTW they loookin nice man n once u see the first hairs THAST when flowering starts rember that... 12/12 started 10 days ago for u
