Idk what’s wrong, spots on plant

Justasmoker33 · Jan 19, 2022

I have a thorsberry about a month old, so you can tell it’s super stunted but I don’t know what caused it, but it has spots on it. It’s possible that it was under watered. I didn’t realize how fast coco dried this is my first time. Any help would be appreciated.

The spots look like calcium deficiency but looking at the rest of the leaf it appears you have a P or K issue.

Not 100% on that. Hopefully others will comment.

If you let it dry out it probably has multiple deficiencies. How dry did it get?

Pretty dry probably too dry, in a pot that’s too big so I tried to go give it too much but didn’t realize how fast it was drying

Yeah that’s what I was thinking from my research, I gave it some cal mag yesterday. Hope it doesn’t get worse

If I remember right, P or K issues can lead to C deficiency because they work in tandem. HotrodHarley is right. Drying out your medium can give deficiency just simply because the capillary action has been halted. Hard to be healthy when you can't even eat. If watering doesn't help alleviate your symptoms I would come back here and ask some more questions.

Best of luck!

Drying out your medium also kills off your microbes. Adding some back would be a good idea.

Coco should never be dry, problem solved. Start watering until you have a little run off from the bottom of the container and water whenever the pots feel light, never let it get dry or you will get deficiencies like what you're seeing.

Feed every single time in coco at low strength then slowly bump it up until plants show issues then back it a little and you'll be golden. All plants are going to eat differently too those feed charts are just a good baseline to follow. Some plants will need more or less.

Sad to say I’m using dry amendments for this grow an didn’t know about the challenge involved, gave cal mag phd to 5.8 last 3 waterings using only phd water at 5.8. I have a couple other plants in the same setup minus the oversized fabric pot.
