@kekon

I recently have many stunned tip in new leaves of amazon sword. After few week of introducing into the aquarium, they start shooting new leaves. But somehow, it is been quite long, and they haven;t do anything. Some appears wrinkle.

As you suggested: Ca = 32, Mg = 8, Na = max. 5, NO3 = 5, PO4 = 0.2..0.5, K approx. 30 ppm, Cl = 5,

I might think that my water dont have enough Ca because i didnt dose Ca and Mg. But just now, according to the water quality report, i found my tap water have Ca is 67 ppm and Mg is 20 ppm. So i think they have enough Ca and Mg for plant.

I can't think of anything else right now. I have over 65W over a 29 Gallon. With 1 2L and 1 4 L DIY CO2 and EI dosing method, I hope I achieve the balance between CO2, light, ferts .. but guess not, stunned new leaf, the tip become yellow and look transparent. Some old leaves died off ( turn yellow, with brown spot)

I am looking for everyone advice.
