First time growing/Need help in late flower

it'll power through. You'd be amazed at how poorly you can grow this plant and still have a harvest. As long as the canopy isn't dead, it's worth pushing forward. somethings to fix next time - don't defoliate. All that did is make your plant less robust to problems... less room for error, smaller yield.. and zero benefit unless talking to some bro-science fanboy/girl. More light. You need stronger light or grow in a smaller footprint with your current light more focused (i.e. hung closer). Maybe the defoliation is part of the limited production, but probably could use more light too. 35-40 DLI at diode is generally a good target to hit. Read the wiki on Daily Light Integral. I'd reduce N a bit (glossy dark leaves should slowly get better.) Looks like low K, too. A couple adjustments might help. Things don't happen overnight, don't do too much too fast.
