Some questions

[Sanips]

Hi guys, I wonder if you could help me about some worries and questions I have about certain palms I own.

First, I've a butyagrus, a JxB F2 and a Livistona nitida which their newest leaf are very yellowish. I wonder If it's normal or it's caused by some short of defficency (iron perhaps?) or overfertilizing them (I use Palm Focus once a week or every 15 days and I always give them the amount recomended (5ml per litre). I leave you some pics about them. The 3 first ones are the butyagrus, the next 3 are from my JxB F2 and the last 2 are the L. nitida.

The second question is about my Sabal uresana. is It alright? I leave some photos. Don you think is too layed? is the soil level too low?

Thank you guy in advance.

The Sabal looks ok to me. — But what is the soil mix of the other seedlings? Pure quartz sand?

No, only the top is covered by a layer of coarse sand. I was told this would be a good method to avoid fungus gnats and I think it has worked somehow. The mix is like a cactus soil with a bit part of sand.

The trace element deficiency may be caused by your inadequate soil mix resp. drainage.  It looks to me like a poisonous NO3 to NO2 reduction. If you had mixed lots of the corse sand into the soil perhaps (?) you would not have that problem.

That would be weird because I found the drainage is way fast and other palms which are outdoors are performing great . The pots are like a grid at the bottom.

Too much to learn about soil mixes . If next leaves continue to showing that colour, I would change the mix for sure.

Outdoors is a total different matter: The soil mix dries out much faster so that the roots get enough O2. When you use a cacti mix for cacti (indoors) you have normally very small and shallow pots. And you need not water so frequently as for palm seedlings.
