Not to be rude, but do you purposefully ignore the most important requests when people are trying to help you with your problem?

Yes MG soil is bad.. yes it is probably causing your problem.. and YES there could be a multitude of other things adding to this that would just continue to give you problems unless you address them; However you will never know because instead of following proper procedure to get your problem answered on here you just take what you need and filter out the rest.

FILL OUT THE FORM... IT IS IMPORTANT.

Unless you don't care about your plants or care to learn what is good and what is bad.
