I have been told from a great grower off of here that you can't really give to much cal/mag. I hope this helps

What's happening to my plant?

Yes you can. So that "great grower" isn't that great.
Too much Ca or Mg can lockout other (micro)minerals.
I am simply passing on Information I have been given.
The grower is a great grower btw, you probably know him quite well depending where you drop in off of here. He likes things to be kept simple and advised not to worry about giving them to much cal/mag. Hey who am I to help.
Peace out

...sorry to see her not recovering mate! pH's look OK; I think this is the solo cup root cramping coming back to bite you,... if the roots are damaged, and cramped, then they have no room to grow and replace what's dead,.. no new roots, poor nute uptake, and then she must turn to eating her fans, which don't have all she needs because not all nutes are mobile within the plants (meaning once in established tissues, they can't be translocated to new growth)... this is why 16oz is a serious challenge! Nothing to do about her this late, but keep feeding as best you can.... is the other one in such a small cup too?

... same plant as in the other thread here? no need to open two of them, so I'll combine,....
Are you under LED/COB lighting? I need pics of the leaves too so I can confirm symptoms,... that said, often the base nute Ca and Mg content isn't enough,...
Konop, James-- I bet I know who it is! I have advised him to be careful, and there have been some hiccups,... truth is you are both right... the threshold for too much Ca and Mg is very high, but too much will certainly cause pH and nute salt content issues,... common sense, understanding your nute element contents, and experience help determine the 'too much" range,.. how much run-off you get is a big factor,.. coco's Ca hogging is another,...

I have 2 plants going in 16oz cups right now. One of them is totally fried. The other is beginning to show some signs that she may soon have the same issues. Yes I am under COB LED lighting in a small Grow cabinet. I apologize for cluttering up the board with multiple threads.
Is it possible this could be caused from bad ph? I have noticed the coco has been drying out a bit between feedings. Since noticing this I placed the cups into a hempy type container. The coco remains moist and since doing this my ph doesn't drop in runoff. Keeping my fingers crossed.

:smoking: Good to hear BigD'.... coco is a good choice for small grows, but in many ways it's like hydro, they way you feed daily, never use just plain water, pH around 6.0,.... Yup, never let it dry out! This makes the pH go way off, roots hate the sudden jump in dissolved nute concentration, and rehydrating can be a pain if it become hydrophobic,... (a wetting agent is called for there)... At 16oz, this is serious challenge and a pain, I'd look to a large pot in any case; root crowding will always make for more difficult, high maintenance managements,...
