Does anyone know what the problem is?

Tips of leaves turning a brighter green/yellow

Possible mag deficiency + N tox + low humidity, could be a combo.. definitely N tox (clawed tips)

Potassium deficiency

It can’t be cause all the older fam leaves at the bottom are nice and dark green

Micronutrient deficiency. Couldn't tell you which, because I haven't had many micro deficiencies. Without looking shit up maybe Manganese or Iron. But that just a guess.

But first I'd check pH. If the pH is off they can't get the shit they want.

So why don’t you tell us more information. The regular stuff we need to do more than guess.

It’s all organic I only feed her compost tea

You are seeing a start of potassium deficiency.
It starts at tip - it looks like nute burn. But the symptoms will move up leaf margins and tip going necrotic.

Top dress ( dry fert ) so medium can be charged and amendments to begin to breakdown for extended feeding. You can also top dress ( fresh soil / water in ) to help “ recharge “ medium.
