Yeah its totally smokable, Looking really good. +rep
The light green, yellowing, could be a sign of N def. What brand nutrients are you using? How much? Do you monitor the ppm? ph?
Some of these questions can help us identify your problem more accurately.
Good Luck, happy growing

the yellowing is totally normal but the large brown blotches look like phosphoros deficiency to me. If your only 5 weeks in you still have time to fertilize at least one more time. Don't worry it will still be great smoke and the buds look pretty respectable for 5 weeks. Depending on the strain you got at least 3 more weeks.

Sorry man Im not familiar with that line of nutrients.
I do know that you should increase the amount of nutrients as the plant gets bigger. Dont follow the directions on the bottle for the entire durration of your grow.
It looks like a defficency, So I would add more nutrients and make sure to ph the water.
Good Luck
