PLEASE HELP ME SAVE THIS BEAUTY !

Hey everyone. This is one of the girls from the first grow. They arent done yet. Here are some details. When i noticed the rusty leaves i quickly PH water and SledgeHammer Flushed by FF. I then fed them half strength Nutes ( FFTB 1 tsp and FFBB 1 tsp + cal-mag 1 tsp). The leaves keep getting worst. Im afraid that these leaves wont recover (which i pretty much know from the forums its pretty much over for them. I am using FFOF and using FF TRIO and CAL MAG. Temps are average 82-84 hi and 68-70 low. under 1k HPS. i usually PH 6.5

2 more pictures.

There are 2 issues I see here...1 Calcium deficiency (explains the orange or rusty spotting) take a look here: http://www.growweedeasy.com/calcium-deficiency-cannabis

2. An over worried and over-anxious parent. Don't sweat the small stuff...you have cal/mag which will very much help the issues you have. Your gurlz are nearly finished and with the exception of a few minor nutrient problems they look fantastic! Nothing kills more plants than their parents 'loving them to death'.

Thanks for the props in asking my opinion, I am flattered. But, you have done a great job in your first grow and things will only get better from here on in!

Good Luck and Great Growz!

how much cal-mag should i put into my feeding schedule. Im in week 11. So about 4 weeks flowering. And you offered to help in your video so i kept you in mind haha. Thanks a lot, i just need to know how much more cal-mag into it. And i know, i have been trying to be careful. If it was possible i would nuke them with food to make them grow faster lol

It looks like manganese deficiency...Get some "Pennigtons Ultra Green Plant Starter" and give it a good dose.....Walmart sells it
