Calcium deficiency?

I don't know how much lobster meal or gypsum you put in there, but I know calcium deficiencies in soil are rare, especially when using tap water. I see you are using RO, but I would still take a closer look or wait for some better advice. Typically signs of calcium deficiency (which is what your leaves look like, without more information) are rather a lockout caused by excess phosphorous.

I would be careful before adding more calcium.

If you let your soil dry out and your ec spikes your pH will probably drop out of the range that calcium is readily available too. It's rare in an organic system but I've definitely seen it in multiple different media/nute setups.

Also I'm not sure about phosphorous but I know for a fact that high potassium antagonizes your calcium uptake, and that's why you push calcium through veg and replace a portion of it in flower with potassium because the plant takes them up interchangeably to build cells if I remember right.

Hey everyone-

So my new round of seedlings seem to be hating me. The mix they are in is the coot mix with slightly less then 1/3 worm castings. Maybe 20%.

not sure if I need to rethink my seedling mix or if I need to get a ph pen to check my water. I was really hoping to not have to ph water.

is this also a calcium/magnesium issue? Roots Organics makes a cal/mag dry amendment. Should I try that? Any suggestions would be appreciated!!

Looks like Iron deficiency,your mix is too hot for seedlings.Or your pH is high blocking the Iron.

Damn bro im having a couple of plants showing kinda the same symptoms… i wonder what it is…
They were over watered at first so i let them dry out a bit and then they started showing those symptoms on the tops… i plan on transplanting tomorrow hopefully thatll help.
Thinking i might have added too much dry amendments..
they’re in one gall pots so maybe a tad small for organics, i was trying a living soil with that size lol..
i know..
I do have some mycelium going on so hopefully they’ll be better soon..

My guess is lockout since you probably mixed your own soil and might have done something wrong.

Cal defiency the plants have already burned through

calcium semi mobile nutrient, and actually its a self proportioning nutrient, and dmg can be permanent visually but internally the plant is fine

Who can really say for sure.. but to me, that looks like a toxicity of Potassium.. or at least that's what my plants looks like once, when I fed them too much potassium sulfate..

It also looks like it was momentary and your plant is starting to grow out of it..

Good luck!

Quit RO water right away. What do you mean scary.
And small boy filter can make most water pretty decent.
Ro is horrible for soil grows.

Why is RO terrible for soil grows? I was thinking of grabbing one because of the high calcium carbonate in the tap water I use. (300ppm). I read an article that the calcium carbonate can build up in your root system and eventually cause a lock out. That the rain water this plants get in nature is soft vs the hard tap water caused by high calcium carbonate, that an RO could help. Also there's been discussion that the calcium carbonate from tap isn't readily available for absorption anyways so your really killing this plants with the lack of calcium as far as feeding goes in some instances.

Mineral hardness is made up of the levels of calcium and magnesium dissolved in water and is the key cause of water problems in cultivation facilities. High levels of hardness in untreated water will lock out key nutrients to plants and also form scale on equipment and tubing.

Calcium and magnesium are the most abundant minerals in tap water. The most typical form of these minerals in water is calcium carbonate and magnesium carbonate. The molecules of these compounds found in untreated water are far too large and immobile to be absorbed efficiently by the roots and transported to where the plant needs them.

Excess Ca can totally fuck shit up. You'll see Mg and K deficiencies first. But that's not the OPs problem.

More like a lockout of something else from an antagonistic relationship with the shit he added.
