Are my plants heading to death
yes they will survive put a wet towel in front of your fans to raise the humidity for a few days and mist the plants often for the next few days , some of the leaves may not repair themselves but dont remove them unless the are 50% or more damaged & maybe raise the lites ?
have started to do so raised the light already is 24 to hot ????? on a hot day like today stoping it from getting that hot is hard unles i had a cooling fan may also need a bigger fan whats the chances of servivel
no worries the plant will survive 24-20C optimum temps, but airflow is important the higher the temps
