Hi All,
Please help me diagnose the problem.
Soil, Bottle nutes (last watering was without nutes as attempting a "natural flush"), no nutes in maybe a week or so. Approx 20 days left based on prescribed packaging. Want to make sure these survive until harvest!

Appreciate the comprehensive reply, you have certainly put my mind at ease! I will ensure the pH is high enough to facilitate any potassium that is already available. Thanks very much!
As a part of the plant’s life cycle, it is normal for some larger fan leaves no longer required by the plant to die off. The plant is putting effort into flower production and less into maintaining fan leaves which are used for photosynthesis to grow bigger roots and canopy. It’s no longer growing roots and canopy. It’s focusing on buds. All the roots and canopy were just to set the stage for the main event: bud production.
Having said that, it’s not uncommon for a plant to begin to show potassium deficiency during flower as it’s deman for potassium rises. You could add PK boost but at this stage I wouldn’t recommend it.
the last three weeks of the plant’s life without nutrients to naturally flush with dechlorinated pHed water is a good strategy. Getting this type deficiency is the result and should be expected. you may have started a week or so early but such is life.
I believe it will survive to harvest with this strategy. If the sight of the chlorotic leaves bothers you remove them.
