It's not new, but part of the reason she has so few leafs on the bottom. She dropped them when I transitioned her.

Fertilizer could very well be an issue, I don't really have any idea how much fertilizer my plants need and just give them a all a bit biannually (usually in the fall and spring).

Then that's the problem. You don't "fertilize" with LECA, you add the nutrients to the water every time, giving you more consistent conditions.

If you only add fertilizer from time to time, you'll get a huge amount of it instantly, too much.

Try using 1/4 strength for the darker season, and 1/2 strength in growing season to every irrigation water, and remember to flush it from time to time, around every or every second month, depending on how much it grew.

Remember to use a fertilizer that also has micronutrients, preferably one that's made for hydro. The best option would be to use a two part fertilizer with rain water.

Oh ok, I do add it diluted with water (a bit stronger concentration then per the bottles description for hydro) not pure. Adding it every time I add water would be way too much nutrients, right?

The idea is following: Let's say the fertilizer tells you to use it once a month, so you currently add a big amount (the recommendation on the label) at once, and water the rest only with plain water weekly for example.

This creates a lot of stress, and the plant has to use it up completely until you dose again in 4 weeks.

Instead, you fertilize with 1/4 every time, but water your plant 4 times a month, which spreads it out better. Continuous feeding doesn't dehydrate the roots as much.

Also, don't forget to discard the leftover nutrient solution every few weeks or months, since it contains lots of waste.
