Those leaves are in the middle of the plant and some top leaves have the same problem, when i water them i allways do it carefuly, so they dont get wet.
i looked the pH in the soil, and it is 5, but the water what i use is 6.5.
Is it possible that the El Nino is very sensitive for the pH? (the two other type of plant is growing in the same room and they get the same water like El Nino, and they have no problems)
Should i wash through the soil with fresh water?
Thanks a lot
