@horsemouth i did not agree with u, i give nutrient (300mS,800mS,1200mS,1800mS) in relation to the stage of the plant +- , so seedlings , veg, stretch, flowers.
In soil ,nutrient and then 2 or 3 times water based on how much the plants eat and maybe your water source. With half dose he can have the same problem and burn the roots if the soil dries out with to many nutrients ( the ec rise up) and thatās why a loot of new growers overwater their plants, cause itās the only time they see them a little bit healthy.
Soil is not inert like coco,is much better to alternate water and nutrients.
Why you donāt like to soak all the soil? Poor roots, you have to water untill the runoff to have a good root structure inside your pot, and then eliminate the runoff after the soil have soaked up all he can. Then u wait obviusly the soil to be well dry , u can check it from the weight of the pot from top to bottom.
