Newer growers need to pick up on the fact that plants are not people. People need lots of food when they are infants and as they grow up they get unhealthy with too much food and die with too little. Plants are the opposite, they need almost no food when seedlings and too little food makes them unhealthy but too much will KILL THEM. Stop thinking of the plants as people.
Growing up everyone seems to think plants need nutrients to grow so when a problem pops up they figure adding more nutrients helps, hence nutrient burn is the most common problem. Sometimes giving no nutrients feels like its neglecting a sick plant but it is often the cure... fight your instinct to feed it.
Now that it is apparent to everyone that ES just wants the plant to die... do what is smart bmw... flush the soil out to at least get rid of the nutrients you just added to it(which will only worsen the problem).
