Deficiency getting worse 😫

Did you attempt to treat it with Epsom salts like I suggested in your prior post? If not, its cheap and very effective! Are you still trying to treat a magnesium deficiency with Cal-mag? Over-use of cal-mag during veg leads to lock-out ... and a toxic abundance of calcium will lock just about everything else out, especially magnesium. Please, go back and read through what I wrote in your other post. Please answer those questions about your grow routine in your next post. Without those answers, nobody can really help you out because its simply a guessing game. And honestly? Some of the suggestions some of the people have posted will only make your problems worse. Again, this is not going to be an over-night fix. Its going to take a week to 10 days for your plants to show real improvement.

Might need more runoff with your feeds and to water them more slowly to ensure everything is getting wet and fresh. Your feeding them with AN feeds, they tend to be stronger ratios then whats needed sometimes. guessing this by the one diary on your profile and if its the same.

Considering the extent of this, I would immediately begin a flush. You're going to be lagging about a week behind the problem with your solution, which will likely be the amending/restoring of your soil after the flush. Like others have said, some thoughtful pruning might be beneficial here as well.

Could be a few causes, I guess you’re growing in brick coco. Did you buff the coco with cal mag? For long enough? If not there is an excess of sodium and potassium in your medium, salts have built up around your roots. This shows up as a ph issue, that can also be confused with nutrient deficiencies. The problem is not your nutrients, it’s the medium. If you are still in veg. I would soak the medium in cal mag or dolomite lime. Cut back a lot of the growth and let it repair. But really, I don’t know what you should do mid grow. There are many opinions. Or even take a cutting and start again in a buffered medium
