yellowing and fallen leaves / bronze curled and brown leaf tips

Howdy. Right off the bat I'm seeing a potassium deficiency. Not over watering, but a lack of nutrients to help carry her needs atm. With a balanced feed, these symptoms will pull back, but not completely. You may lose some of the more affected fans, but all should be well with new growth after the application. A little patience and a couple normal, balanced feeds and things should be right as rain. Cheers and good luck this week👍

off the top of my head .... I've no idea? But..... Looking.... It is only the Fan leaves which logic would say is some sort of self preservation. Its choosing the leaves it doesn't need as much. Too hot or too cold? not lack of water though, it wouldn't choose the fan leaves specifically for that I don't think? It would just chips from all the tips..... Onlly guessing but good look

Привет, бро! 👋 Это общий дефицит элементов из-за нехватки в поливе. Увеличь объем полива с 0.5 литра до 1 литра. В таком возрасте растение пьёт 10% от объема горшка, т.е. если у тебя горшок 15 литров, то поливать нужно 1.5 литрами воды, а ты поливаешь слишком мало. Увеличь полив до 1 литра за раз! 👌😇👍 Удачи, бро!
