Deficiency?

At this stage of flowering there is nothing much to be done, besides stop giving so much nutrients. If the plant is not dead it will keep feeding from itself, and you will see yellowing and leaves falling, anything like this is better than nutrient burn, and you don't destroy your soil, something really important if you plant to keep it sustainable and you cycle your soil. All in all, they don't look bad at all, they're just in that stage of growing, really close to harvest, and there is nothing much to be done, they really needed those nutrients two weeks or so ago, not now, so adding nutrients now it's kind of worthless, let's say they are using Nitrogen but they're not uptaking Nitrogen (from roots), if it was stored on previous weeks fine, leaves won't yellow, they will only go from dark green to light green, and move on. Really looking forward to next weeks of progress.

High there! First brown curled up leafs tips + some yellow leave(not the second pic) look like nutrients burn. Consider flushing those ladys with 24C/6.5 PH water to wash away excess nutrient(3x the pot size) For the yellow leafs of the middle picture its look like nitrogen defiency, not uncommon at this stage. To avoid problem like this : every 1/3 watering use only plain ph ajusted water without any nutrients. Enzymes can help you to recover some lost root mass after a burn.
