Top set of new growth part is a little crispy and curling taco style. Is this down to heat ? Growing in greenhouse in U.K. other plants are okay and I do have a second plant in the same pot that’s perfectly okay ?
Curling upwards like a taco is heat/light issues. Turning down is usually a root issue. Maybe not enough/ to much water. Make sure to water slowly, until you have a little drain out the bottom of the planter.
