A friend of mine has this plant and its growing some weird colas after topping. It was topped at the second true set of leaves. The fist set has single fingered leaves where as the second has 2 fingered leaves 4 colas in all. And the growth started out light green and is slowly turning green
Little too Hott for that little one plain ph'ed(6.5)ish water for the next watering. When you topped it that was stress on the already hot soil, just give plain water for the next couple waterings with a little run off should do it what Grow medium are you using? Soil or soiless mix?
Same as i said before then that should only need plain water for the next couple waterings if you want to help with the burning a little quicker use a little powdered gypsum and yucca extract with your next watering, those will both help smooth out an organic mix. The gypsum will add much needed calcium and a future buffer against excess salts or burning
