plant has been getting progressively worse with this deficiency. Hit it with cal mag, 2x, no better result. May be from over watering, I flushed with 3 gallons before using the cal mag, while the medium was still a bit damp. And 2 gallons with the cal mag 3 days later. Has only been doing this since about 3rd or 4th week of flower, and today is the 6th week of flower. Really cant lose this plant but I've tried all I know to do. Its mostly the top of the canopy and my larger fan leaves. Maybe 20% of my foliage at this point is fucked and burned up completely.
Need help asap. Leaves burning quick

Not really a deficiency to my eye more likely too much.You are feeding too strong and or too much. It happens trying to pump them. Flush with water. A lot, twice as much as you think then more. This should also make them swell too. Wait one or two weeks before feeding again.

You don't mention anything in terms of what you're feeding, or how much, so I'll go out on a limb a little. Your plant looks short on Ca, and 2 days of treatment using CalMag isn't going to fix it, nor will any amount of flushing. The damaged leaves will remain that way, you just want to see it stop...which most likely will take daily Ca to stop it (you're in flower and Ca generally has N attached to it, so be careful). You look a little short on P as well. It appears you have pests as well, so I'd go over all those leaves with the little white dots along the veins of your leaves. Good luck.
I feed only when I see a slight droop in my leaves.
May over saturate a bit but never nothing to drastic. But my other plants are healthy and green as could be. And I checked the insects issue, couldn't find anything living on the plant or in the tent. I know the dead and dying leaves are gonna remain that way, but im just trying to salvage what I can. And I hit it with cal mag over a week ago. So your saying sort of micro dose it daily with cal mag and see if that changes the result?

I wouldn't stop feeding your plant and keep adding the CaMg. Used to struggle with Ca issues a lot until I switched to Jack's 321. Now I might get a spot here or there and I just increase my PPMs. You might want to look into it; cheap, effective and easy.

Yes...a little every day, both Mg and Ca...and separate from one another as well; if you can. (In other words in the form of Epsom for your Mg and CaNi for your Calcium...again be mindful of the the N component if you're in flower. ) Good luck.
Some of my plants did the some the first weeks of flowering. Maybe that's a period when they start consuming a lot and deficiencies are shown. Never gave them supl cal mag. 2 fan leaves just died and some still having spots but it stoped. The buds are a bit smaller than others but hard as rock.
I hear yall. And I appreciate it. I been photo documenting my canopy and it has seemed to stalled the spread of it eating itself. But my feeding has been the same since flower in the amount. I just need to start documenting more and making sure I'm hitting the necessary food at the right times. Every strain in different.
I'm at week 5. I thought it was 6. My bad. Plants need to tapered down off the nitrogen starting week 6 right?

Taper it off when the plant lets you know to taper it off...I don't worry about time, I worry about the plant. But in general, yes, you would need less N as the plants progress to maturity. Good luck.

Your dramas are being caused by under watering mate. Your building up salts which is causing lock out.
Get some nutes, check the ph and ppm.
Run them through the pot and collect the first 200ml. Check the numbers on that and you'll be able to see it.
Coco is hydro bud. Doesn't work right if you treat it like soil. Gotta water every day to full saturation at least once to get a sweet run.
