Have you checked your plants for bugs by chance? The leaves look like you have an infestation imo.

What about heat

 

[baldwindabs]

well i know the biggest one is getting a bit heat burnt i ran out of space so there was nothing i could do about it, the other plant isn't as bad but its not that great looking the buds dont seem to be affected they are still growing quite a bit could this just be because they are almost done? i know a few people who grow purple kush and they told me 8 to 9 week flowering time and the website i bought them off of says 7 to 8 weeks flowering time

Yes looks like heat to me and a fair bit nute burn to

 

[CoralMafia]

I agree heat stress and nute burn

 

[baldwindabs]

[baldwindabs]

i gave them half the normal nutes this time around should i do a full flush with just phed water?

I was referring to the 4th picture. Look at all of the leaves. I agree with heat stress also but look at all of the blotches on all of the lower leaves.

I was just have a look at flowering time it says 8 weeks. They must be very close to pulling them
