I got this plant like two weeks ago or so. It had some yellow leaves already so im not sure but i feel shes not happy, some leave keep yellowing and i havent watered since i got her. I have a moisture meter and it says she is still moist so no need for me to water. Ive asked around and people say it might be some sort of mineral deficiency. They say nitrogen and stuff. She was in a north facing window but today i moved her to a south facing one to see if light was the problem. Can you guys give me some input?

Was your plant showing yellowing foliage when you first got it or is that a development only since you got it like two weeks ago?

Don't rely on the moisture meter as they are often very inaccurate and misleading. Stick your finger into the soil down to your first knuckle. When the soil is dry that deep, then it is ready to be watered.

Is your local tap water on the hard side?

Can you post one good photo that shows the entire plant, including its pot? How a plant is potted often matters a lot. Did you repot it?

Yes it did have some yellow leaves when i got her. I live in LA so i think the tap water is hard but i have a britta filter and thats what i use for my more sansotive plants. Otherwise i let water sit in an open container overnight then i water. The plant is still in the pot it came in plastic 6in and i havent repotted yet.

Your plant is in its nursery pot and is well-rooted, so that means it cannot go two weeks without getting water. Discard the meter! Water as soon as the surface of the soil feels almost dry to the touch. I would estimate that to be about once per week. When you do water, do it thoroughly until some water runs through the drain holes. That means you will probably have to take it down and water it in the sink.

I am not familiar with LA water. Hard water has an excess of mineral salts in it and is often hard to get soap to lather with it. Letting the water stand overnight does nothing because the mineral salts do not evaporate. The filter, however, should take care of the problem.

Quick update on the obliqua, i watered her as soon as i did this post and she has been in a souther facing window with a sheer curtain. I watered her the same time as my maranta. Today I watered my maranta but when i touch my obliqua she feels not dry just sort of damp i guess could be the word. Its not wet not dry. I put my finger to check and none of the soil sticks to my finger or the moisture meter but it doesnt feel dry. And she still puts some yellow leaves. Im not sure if its maybe the soil down in the roots the problem that holding too much water but it wories me. Im thinking about repoting her just to be safe but i wanna pass it to you. I also will attach a picture how the center looks. Its less yellow leaves than before but they still show up.

The soil does not have to be completely dry. Almost dry or slightly damp as you described is fine. Occasional yellow leaves will always happen, especially if you fail to keep it pruned back and if too much light is filtered out by the sheers. The fact that you are getting fewer yellow leaves is a good sign.

I understand the temptation to explore the roots and remove what you suspect is some disease and replace the soil. It is a common feeling, but very misguided. The root system is the nervous, circulatory and pulmonary system of a plant all rolled in one. As soon as you start poking around in there, the potential for damage is far greater than the likelihood that you will make the plant better.

Don't fuss over every leaf that is discolored or slightly damaged. Nature is never perfect. Do what you can and enjoy your plant without worry!
