og kush week 4 flower how am i doing?

I am currently at week 4 flowering og kush. This is my first successful indoor grow so im just curious as to how much more bud production I will see in the next 4 weeks? Is there any way to maximize yield at this point? Well anyway im growing in a very limited space and have utilized some lst. Im running a 400 w super hps plants are about 6 in. Away from light no burning. Running a partial fox farm feeding schedule (tiger bloom, grow big, open sesame, beastie bloomz, cha ching. ) for some reason my phone is not letting me post pics so I will try to post some soon

Best way to max yield is not to try any thing fancy and have a blow up the last few weeks. Looks like your doing well just keep it going
