Just because they are white, doesn't mean they are mature. Over time they will grow in size until the head becomes too heavy and they will start to bend under their own weight. Slowly turning amber when over ripe. They may be white, but not right! Good luck
Hola,
En la semana 5 si ya vemos tricomes blancos es bastante normal, son tricomas de las semanas anteriores que estan madurando, hay que tener en cuenta que solo faltan 3 semanas
Usually starts on the sugar leaves then your buds are last to develop the milky or amber. Thats why a lot of people save there trimmings because they are full of mature trichomes and good for bubble hash.
