Tall, lanky outgrowing room, snapped stems, bending, stressing,.small branches.
Pre flowering, looking female, except 5&6 stunted, possibly males.
Plant 4 is the most female looking. They need another week to start flowering so I can tell for sure. All the tall ones, 1-4 are probably female but uncertain. 5 and 6, on stools seem more male like in top.
