Low light or CO2. Increase light and CO2 to tighten the whorls into dense conifer-like columns.
Pale or yellowing tips
Iron or micronutrient deficiency. Dose a complete trace/iron fertiliser and stabilise CO2.
Algae on fine leaves
Its delicate needle leaves trap algae if nutrients are off. Keep parameters stable, ensure flow and add cleanup crew.
