Dont be a douche, nobody is here at your beck and call. usual response times are counted in days, sometimes weeks. rarely hours. you don't need to get all pissy that nobody has solved YOUR problem for you 11 hours after your post.

aside from that, you have not provided enough info. We don't know how many weeks in bloom, and at what locations on the plants it is occurring (lower, mid, or upper leaves)

I would check out the pics at Grow Marijuana FAQ, Cannabis cultivation - marijuana growing tips & photos

it looks to me like like a K def, like figure 13 which progresses to look like figure 14 at the above link.

I would increase the amount of big bud you are using as it is around 4% K or find another additive that has higher K levels and augment with that. they really love their Potassium, and during bloom the flowers are eating it up at a very high rate, so the leaves show the signs.

in my opinion, people often misdiagnose the burnt leaf edge as an overfert prob when an overfert actually looks like figure 4 in the link above.

overfert is when the nute solution ppm is so high that water actually comes out of the plant roots and into your solution because of the osmotic pressure difference, it is more of an even crisping dehydration of the leaves from the tips, but affects the whole leaf, the entire surface, not just the margins (margin = blade edges)

if you have green and reasonably health centers on your blades, its not overfert yet imo.
