What is wrong with the new leaves on my Calamondin? At first they were just fine, growing nicely upwards, and then about a week ago they seem to have gone downwards, it looks like the leaves are too heavy for themselves to hold...
Does this have to do with the fact that I repotted this tree when the branches were starting? But they were fine at first!
Here are the pictures. Take a look:

When I transplant from the ground into pots they droop alittle like that so they might just be alittle stressed.
They might also need some water they look alittle thirsty

Hm, the other tree seems to be doing the same thing:


What's going on? How can this be fixed?

Right now they're standing on a south facing window. Do I get them out of sun? Is it too much fertilizer?

Please help !

Oh, and also some of the old leaves are turing yellow and falling from both of the trees. What could this be? Any help would be really appreciated!

Millet, maybe you know this one?

Oh, and also here's my fertilizer schedule: I fertilize at a rate of 300 ppm Nitrogen per watering, with a NPK 6+4+6 citrus fertilizer.
I stopped fertilizing for now to see if that helps.

How much do you water?

How wet is the soil?

Exactly how much fertilizer do you put in how much water?

Stop fertilizing, and take them out of the sun for a few days and see if that helps.

well look what I did today

I changed the CHC from Exo terra with one from JBL which have a greater quality and did a mix like this

1 part CHC chips+1 part peat+1part spaghnum moss+0.5 part of perlite (big size)

and surprisingly the leaves were pointed upwards this evening and not horizontally or downwards like few of them this morning

What I wanted to say is maybe they don't lack water but air.Just a supposition

Stop watering, stop fertilizing, remove from sun.

The next time you water should be when the soil is dry (not dust!).

Get a wooden dowel or stick, push into soil. If stick feels damp, wait another day.

Well, normally I don't stay too long at home, where these Calamondins are located, but now that I am, I can totally see why this is happening! Right now it's +35C(+95F) in the room perpetually! Good God! Can you imagine what's going on on a south facing window during these heat waves? I immediately removed the trees away from the windowsill, a few feet away from direct sunlight. Hopefully the shadow helps.

And if the shadow does help, how do I get them back on the windowsill when it cools down a little bit? Do I do it gradually, by, say, putting them each day a half hour longer than the previous day on the windowsill?

I think if you moved them closer over a period of a couple of weeks they would be fine.

A little update. Here's how the trees look today, after they've been in a shadow for some time:

Comparing to the last pictures of both trees I posted I can see pretty good improvement on the tree that is standing on the right. The left one is still a mess .
As you can see I removed all of the fruit from the left tree, because they were old and very soft, and I was hoping it would help the tree a little.
To me both tree leaves look healthy, dark green, shiny, don't show iron chlorosis, any deficiences, but the leaves on the left tree feel pretty thin, compared to the older leaves, that the tree grew while it was still in the nursery. It's like comparing cardboard to toilet paper... Maybe it's because they've started growing only like a month ago and will get thicker? The leaves on the other tree seem thicker, but also not as thick as the nursery grown leaves.
Despite the improvement of the right tree, I'd still love my Calamondins' leaves growing in such manner:

But I guess you get such leaf growth under full sun outside, huh?
Also the old leaves keep on getting yellow and dropping.

Any more advice?
