Hi @draxler,

Welcome to APC!!

Do you have any water parameter information?

pH -

dKH -

dGH -

nitrates (ppm of NO3)

What are you dosing for nutrients? How much? How often?

Welcome to APC!

In addition to the water parameters above, what size aquarium is it, how tall is the aquarium, and what specific light are you using? It looks like the substrate is just gravel. Is that right?

Looks normal...new cuttings adapting to your water and lighting. Give it time and long days. 12 hours of light. Some might not agree..I read of ridiculous claims of getting lush plant growth on 4 hours a day.
What even keep plants?

Hi All,

Just in case you are curious this appears to be a classic case of boron (B) deficiency. Notice the necrosis on the basal part of the new leaves.

I. Symptoms appearing first or most severely on new growth (root and shoot tips, new leaves)
A. Terminal bud usually dies. Symptoms on new growth.​
1. Basal part of young leaves and internal tissues of organs may become necrotic.
One of the earliest symptoms is failure of the root tips to elongate normally. Terminal shoot meristems also die giving rise to a witch's broom. Young leaves become very thick, leathery, and chlorotic; in some species young leaves may be crinkled because of necrotic spots on leaf edge during development. Young leaves of terminal buds become light green then necrotic and stem finally dies back at terminal bud. Rust colored cracks and corking occur on young stems and petioles, and flower stalks... boron deficiency
Differentiating between calcium and boron deficiency symptoms: When calcium is deficient, there is a characteristic hooking of the youngest leaf tips. However, when boron is deficient, the breakdown occurs at the bases of the youngest leaves. Death of the terminal growing points is the final result in both cases.
