Calcium Deficiency Issues

I noticed my plant starting to show calcium deficiency signs about 2-3 weeks ago. In this time I have been adding extra CaliMagic for each watering, but the deficiency is still getting worse. I am growing in coco/perlite, Fox Farm Trio nutrients at full strength, watering at 5.8-6.1pH with 800-850ppm, runoff pH is 6.1. I use 1tsp/g CaliMagic. All my other plants get near identical waterings and haven't shown any deficiencies. I'm not really sure what to do at this point to correct this deficiency. It is currently in veg, but I would like to start flowering in the next couple weeks and don't want to do so before correcting this issue. Should I flush with plain water? Should I raise the pH up so the plant can take in more calcium? Should I try adding more CaliMagic?

What I would do if I where you would be to raise the pH a tad so the plant could receive more calmag, and also add a tad bit more N to your feeding, let's try that to see if it helps. I do believe that it will. I had some calmag issues recently myself, however what the issue with mine was I would mix the feed up and feed throughout the week with that food. Well little did I know the pH would jump over a period of a couple days, it'd go from 6.5 to 7.5 which is way to high. Couldn't figure out wtf was going on at first till I thought to check it twice.

Here are two pictures of def. One is nitrogen the other is mn or iron, Not sure but it may help you out. If you notice the leaves on the N def. in the back ground are still green that on is sever def. Good luck hope this helps you, If not we can try some more..

I have to add that for the most part when dealing with calmag deffenicy usually iron deficiency go hand in hand.

Thank you both for your help and advice! I'll try changing the pH as well as nutrients a bit and see if that helps :) Have a great day!

You corrected the issue, those rust spots won't go away so you have to see how your new growth does. Def. not a nitrogen deficiency on a plant that small at 850ppm. Clawing leaf tips on lower fans tell you she has had too much nitrogen earlier in the grow. That was her telling you to cut back your ppms.
