7th week

hello everyone my girl is now into her 7th week and she seems to be coming along beautifully, but there is one thing that`s not right : on a couple of leaves (lower) looks like there are small dots and i can feel the spots when i run my finger across them, they feel dry at the top of the leaf but i just wondered could this be that shes mature enough to put into flower hench why it needs maybe phosphorous or potassium to help with her flowering stage, any advice would be gratefully appreciated thanxz stinky

its going well, keep going as u are
