is epsom salt good to put in u'r res? and if so how much per gallon? or is it only when u have problems? and can u put it in right with u'r nutes or do u flush it with the salt and water only and if u do when can u feed u'r plants again?
im using bc nutes i only go half strength. so i can throw like 1 tablespoon per gallon sound right? and can i throw them right in my nute res with my other nute?
