Am i right in thinking this is cal/mag deficiency?

I have added cal/mag to my feed, and given 2 foliar feeds of cal/mag in the last week but it doesn't seem to be sorting it, any help would be great, thanks

Have you checked your Ph also? Just giving her something to help isn't enough. She needs to be within the right Ph range for the best nutrient and mineral uptake. For most nutes and mins 5.8-6.2 is ideal. For example calcium is best absorbed between 6&6.2, much below that and it is like starving and staring at a steak through lexan.
 
I keep my ph between 6.2 and 6.5 as I'm growing in soil and the soil's ph is fine too just checked that this morning, I've been trying to find out what it is all day and im starting to think they're not getting enough calcium and phosphorus, I've just fed the bad ones about half hour ago so hopefully sorts it out, thanks
 
Looks more of a ph issue causing lockout
I run in promix and use water straight from the tap at 8.2
I would stop ph-ing in soil
I ran my last few grows not checking ph and had a lot more problems that this, this grow ive had my soil and feed ph perfect all the way through, to me it definitely looks like calcium and phosphorus deficiency as i have been giving them pretty weak feeds, anyway ill give it a few days see if it gets any worse, thanks
