the key is to reduce the nutrient input where we cant avoid drier air. Simply, as we add nutrient salts to water, and then water evaporates, we are left with an increasing concentration of salts.
So where we are losing moisture faster than it is being replaced, we will see salt accumulation, not usually in veg, but it will show as the plant ages and radicals build up in the cell tissue.
Nutrients are only really effective where our plants are in near perfect conditions environmentally. otherwise they just cause problems in most cases.
