How close to the light are they?

with 2 weeks to go and the leaves turning crispy, I think you would be better off raising the light a touch and getting rid of the heavily damaged leaves to allow penetration and maybe plan on harvesting in 2 stages to allow the bottom to ripen. Just a thought.

mebe. fed them 1/2 str the whole time but sometimes more often then recommended
alaska 0-10-10 only at 5 weeks and 5-1-1 / 0-10-10 before that at half strength or less.
now only brown sugar water xD

Yeah, crispy leaves is the direct or indirect result of overfeeding. Also, yellowing leaves towards harvest should be avoided.

Your best product is going to come from keeping those plants green and healthy until harvest day. I just finished an experiment with B'cuzz HP soiless mix and it turns my plants yellow at day 30 in flower. Something about the composition of the peat-based medium just doesn't work nearly as well as my Sunshine mix #8. My point is, lower your feeding levels, read your plants, and if you still can't keep them green, look for another medium (i'm assuming you're in dirt). Good luck!

Similar question.. The lower lower leaves in the neither regions of my SCROG have been yellowing/crisping and falling off as well, just entered the 4th week. At first I suspected low light levels or lack of nitrogen. I added a bit of grow formula. The thing is, I don't really think it is overfeeding. I have been keeping PPM below 1300 (until yesterday- 1580) and have absolutely no sign of nute burning in the upper canopy. No curling, no twisting, no tip discoloration.
Any thoughts?>

Leaf drop on the lower areas of the canopy is normal to an extent but as you suspected, yellowing leaves that early in flower would tell me to look at my nitrogen and feeding levels. One of the 'issues' with indoor growing is that the light is always directly overhead so if the upper canopy is robust, then the plants tend to drop a leaf or two down low that aren't being used as much for light absorption.
At your feeding levels, I'd keep an eye out for signs of leaf curl and burn and also make sure to keep your medium clean of excessive salt buildup.
I'm not a fan of heavy feeding these days and strains that I once thought did well at 1400ppm are now doing better and yielding more at 1150ppm. Food for thought

You've got some leaf curl in the pics above but they really don't look bad at all. Also, the big yellow leaf in the center looks more like it was bleached from too much light rather than too much food. I'm personally not a fan of soil that has food in it as it's hard to know when the plants have used up all the nutrients without them showing some signs of poor health first. So it really becomes this balancing act of feeding them lightly until all the food in the soil has been used, then feeding them as the plants require. I find it a lot easier to use a promix type medium where I'm able to feed from day 1 really.
Anyways, unless you've got some better pics of problematic areas, I don't think you're looking bad at all.
Oh, I'd ditch the sugar water.

well uncle rico u r right again. using sunset mode on the camera i took a pic of my buddies sog and there was a bright yellow spot where those yellow leafed plants should have been.
his HPS was sagging down in the socket like a boner after sex, creating a centralized hotspot of light
adjusted, took a new pic at the same angle, and plants were visable
