What's Up With This Banana Plant

Recommended Posts

Hi @John Collins

Do you happen to live in an area with hard water or do you know the water parameters of your tank - specifically pH, dKH, and dGH? 

White discoloration on leaves can be caused by a number of issues:
1) Excess calcium (Ca) in the water
2) Insufficient available potassium (K)
3) Insufficient available iron (Fe) caused by not enough iron being dosed or the wrong type of iron for pH of tank

BTW, the "cupping" of the leaves is typically caused by insufficient available magnesium (Mg) which is a different issue.

Hope this helps! -Roy

Hi John Collins,

Try adding Easy Iron or Seachem Iron (per respective directions) in addition to the Easy Green.  They both have forms of iron that are easier for plants to absorb when the pH is above 7.0.

Also add 1/2 teaspoon of Epsom Salt (use the cheap stuff no scents or additives) per 10 gallons.   When you do a weekly water change add 1/2 teaspoon of Epsom Salt per 10 gallons of water removed from the tank.  This should add about 5 ppm of Mg to your water and reduce / eliminate the 'cupping'. 

Hope this helps! -Roy
