well, details are a little important. for instance, the cause of the problem, is (imo) more important than the problem it causes. if an issue is caused by nute lock-out, due to improper ph, then there's your cause. if you simply treat an issue, mag. def. for instance, by giving cal-mag. well, that's not gonna help, because the improper ph will not allow the plant to take in the added mg. so, details enable others to help you find the cause, and not just treat the result.... but whatever, lol...
