flowering?

how long am i looking at to start flowering

You could flower now. Alternatively, you could top it now to create two main stalks before flowering. The resulting stalks can also be topped until you have the number of colas that you want. You need to consider the strength of your flowering light & how far away it will support healthy growth. Then, to find the ideal height to flower at, you'll want to know how much your strain grows during flowering when flowered at that height.

depends on space, lighting, how large of the final container you want to use, how big you want your plant to get, etc.

what is that stuff all over the leaves from?

yeah, i couldnt tell it was water till i zoomed in as far as possible instead of a level down from full zoom in.
