Stop giving it epsom salt...it is obviously not deficient at all... Here is the deal, you have to be really careful of what advice you take and listen to...it is easy to hitch one's cart to the wrong trailer...a lot of times people might get it...but here is a little nugget of wisdom for you to carry with you through all your days of growing...
If you are using tap or well water, or rain water then it is very very very unlikely that you will see a calcium or magnesium deficiency. If you reuse your soil over and over and over and over without giving it time to sit and reamending it, then you may witness a cal/mag issue (or so I have heard)...actually you might get to see one now...If you happened to add a little too much epsom salts, you will get to see one...because calcium will get locked out. The only time I have ever seen a cal/mag issue from adding cal/mag when not needed, and I reuse my soil over and over and over, but I do reamend and try to give it a rest for a few months...I also add new soil every few grows because it goes somewhere...on the floor, under my nails...either way every few months I have to get new, and this is probably why I don't see the issues associated with reusing soil...
But for real, do a lot of your own homework..look at pictures, and not just MJ...try growing some other plants and get the hang of it...there is a lot to learn with doing this...more so than the forum boards alone can do...because anyone can answer your questions with absolute conviction...but some people really have no to little idea what they are talking about...
I just wonder how many people on here have ever even grown a plant... Or ventured to learn more about the one they seem to want to grow, or appear to be growing...just read all manner of things... I have learned so much using this forum to do my own research...as in someone says something and I check all about...going from one pot forum to the next doesn't work though...there have been things about cannabis plants that have been totally made up just on these forum boards, and then it bounces all over the internet, and people that don't know better the world over keep getting whatever it is wrong or what not. ANyway I am high, and going to watch tv and sleep...good luck...don't give it anything else but water, or you'll be sorry...I can assure you this.
