Please - start a diary - that give us a lot more information on which to base our advice! Yeah, your EC is way too high but we don't know what it is you're feeding her and could give you more specifics of what to do to correct this problem (and maybe point out to you what it is you've done to get it to this situation so you could avoid it in the future)!! You see, you're getting a calcium deficiency but throwing calmag at it might not be the answer... I think what's happening (and I could certainly be wrong because I don't have all the information), is that you've overloaded your plant with nitrogen... this can/does cause a lockout of calcium and if that's happened, if you HAVE been giving too much nitrogen, throwing some calmag at her won't correct the problem even if you get your EC down... you would need to flush out the excess nutes and salts and take a different tack when starting to feed again.. but seriously, we need information - a diary will help US help YOU! Just start the diary with as many weeks as you can reconstruct... it doesn't have to go back to the beginning!
Good luck...
