Hey so I am into week 6 of flowering and the buds have gotten heaps fatter and smelling pretty good. I have noticed though heaps of the fan leaves have brown spots and some have a white powdery mildew on them. Would it be best just to harvest before it gets any worse.

Please be kind this is my first grow and it’s been a long one. Over 6 mths in the ground

I see the plants are outdoors, but why are the dripping in water? Your "roof" has holes in it?
Damn dude PM is a bitch and if you don't do something about it NOW, it will only spread and take the plant(s).

Lastly, that's a very heavy sativa Dom plant. They can flower for 15 weeks or longer. I've grown pure sativa in the past and they seem to never finish completely. A 12/12 schedule can keep them throwing more waves of new pistil growth. If you can drop the light hrs down and increase the dark. Maybe put a dark tarp over them. This will force them to finish. That is, if your close to finishing. But looking at the pictures I'd say your half way.

Get that PM under control and ensure good air flow through the plants.. PM doesn't like dryer conditions.

So it had just rained when I took the pics. Should i remove the affected leaves

Affected how? Leaves with mild to medium necrotic lesions or anything still green(ish) leave on. Any leaf that's hosting PM with a "white dusting" is matured and capable of reproducing. These gotta go asap! Search around for a foliar solution product. Solutions with a high pH...ie: silica products, baking soda, ect.

There's also microbial products, mainly bacterial. These can also be included into an existing IPM program. If you choose microbial, I'd suggest combining the microbial solution into the silica and use as one. Microbial can be very low pH in origin and PM thrives in a acidic range. This is the reason why you have PM. Your plants internal pH is acidic, a result of its influencing conditions, (soil, nutrient availability, pH).

Edit: any leaf that is heavily affect with necrotic lesions remove as well. Helping to open up air flow throughout. Try to target overlaping leaves as well. Leaf laying on leaf will certainly trap moisture and this is where PM takes hold.

Address your soil as well. Take some pH readings. You definitely have nutrient availability issues going on. A plant in poor health will succumb to any foreign body.

I did fail to mention that for the last week I had a green shade cloth around the plant and a white one on top as my wife and I went away and I had the mother in law staying over. I’ve now removed it all . Could the browning on the leaves also be from a lack of light?. And the mildew is not not really on a few of the lowest branch’s so I’ve removed them
 
Decieving your mother in law has cost you your grow."He who chases two rabbits usually ends up with none", Confucius.Really use citric acid foliar as per @xtsho .2 teaspoons per gallon not in full sun.
