I'm no soil expert but I would consider several things....overnuting, abnormal soil ph or perhaps they are rootbound. Check out this link and see if it helps.

Good luck.

Would find a new pot for the one in the terra cotta. Roots love to cling to the pores in those, and it can be more of a bitch to transplant, the longer you wait.
Possible ph, possible habitual overwatering....?
Any perlite in the smaller pot? If not, you'll need to get something for soil aeration.

Im gonna repot the little one that was just a lucky seed i found,lol..
The bigger plant came from a cutting, and my friend has another cutting from the same plant. We potted them both the same and feed them the same feed but mine looks like this and hers doesnt.
Its not fair!!!! the ph level in soil and and water is under 7, and i did a soil test for nitrogen as well but the results didnt show i think it went wrong!!
im flushin it with water to see how that goes then im not sure??
any suggestions??

[Weedhound]

Well....how much under 7 is the water and the soil? It makes a difference. Ask your friend to check the ph of her water and soil as well. If you two are using the exact same fertilizer and the exact same size pot with the exact same drainage then my guess would be her water is at a better ph than yours. Disclaimer: GUESS!!

Good luck.

HI unika13, and welcome.

Your plants are rather dark green except for a few leaves I don't think it is a nitrogen deficiency.
But then again I am no expert.

Here is a guide to look at maybe it can help you out.

It would appear that you are overwatering. That won't be the only problem you're encountering but it'll be the first and foremost thing that you'll need to address. The one in the clay pot is worse than the other and it's more than likely because there appears to be little or no perlite in it whatsoever.

Repot the smaller one.. and spread your waterings out more.. you should never be watering a plant more than 3 or 4 times a week... NEVER. No matter what size it is or how old it is.

Cheers,
Bob.
