This chart seems a little shaky to me in a few ways.
For example, Leaf edges brown and scorched. That could be from and probably is from either heat stress, K def or overzealous use of nutes. None of those are even mentioned. Just my 2 cents for what its worth
Im sure someone else will chime in.

Like a lot of charts, it misses the three most common causes of plant problems when growing cannabis in soil.
1/ over watering: roots sitting in water for long periods of time due to bad drainage or to regular watering
2/ over feeding
3/ incorrect watering where the medium is not thoroughly watered thus not allowing roots to fill out the grow medium correctly
These are pretty much the cause of most soil grow disorders and result in roots becoming stressed and stop uptaking nutrients in a sort of domino affect. So if you go merely by the type of leaf disorder which indeed do match much of what is on the chart, then your only recourse is to find an additive that is high in that particular nutrient and feed it to your plants......when in fact its the 'feeding' itself that is killing them, too much moisture in the root area for too long a period.
'Most' disorders in soil type grows would not even occur if growers merely let their pots go light before thoroughly watering again.
Most root bound problems are caused by not thoroughly watering plants, then allowing them to completely dry, then thorough watering again etc. Cannabis can still turn out some nice buds even if 'pot bound', in fact this is a common technique for sea of green growers, but root bound is a different animal, and plants can become root bound even in large pots if not watered correctly.
