watering with chems if the soil is super dry ive personally never had an issue with when I was doing chems,or now with heavier feeding teas n so forth.if your plant is healthy and your Number n PH are all good,I personally dont see the issue unless your really trying to slap n push them hard.Id prime the soil first if it were me,but short of that id personally have no worries about it man.even use a light sufactant to prime the soil too if ya'd like.few drop of dawn original liquid dish soap works really well to a gallon of feed water shook in a little.
