I'm in week 6 of flower grow Sterking haze by Nirvana. I noticed some leaves changing around week 4 or so but it has got much worse. I PH my water and nut mix before feeding and have been giving then foxfarm big bloom and tiger bloom. Temps never get any higher than 81°. Any input is appreciated!
 
Here are some pics

Potassium deficiency. Probably magnesium as well. You can foliar spray magnesium. Are you using any microbes? Mycchorizae?
