Hello, I brought my hortensias inside during winter now and have a growing lamp with blue lights over it for a few hours during the day. somehow after a few days, one of them started to look unhealthy with dropping leaves. I don't know if it is too cold in the room approx. 12degrees centigrade or is it too much water or too little. the other one on the other hand still looks good but losing its leaves and some of them are becoming yellow. Please advise me what to do. thanks Selly
