Some strains get minor burn from bagged soil. ... ph of most Fox Farm soils are 6.3 ... but bump 6.5 - 6.7 to allow drift.
As long as stalk and stems are green you are fine. It becomes an issue when leaf is showing large problems. That soil can feed that plant for weeks. Later , you can grab a bag of ocean forest , top dress and water in instead of using bottled Nutes.
That soil can also be used to make a “ tea “ for soil drench too ( bubbled in cheesecloth bag )
