My plants are under a 600w hps cooltube and yesterday i noticed the leaves starting to curl down at the very tips which i suspected might be because they needed watering but i fed them then woke up this morning to find them just as curled if not a tiny bit more, other than that they seem very healthy but just wanted some input from anyone who thinks they have an idea of what it could be thanks! ![IMG_20130404_085652.jpg](/data/attachments/1826/1826105-f87285f7c4a878d6250c342fde2dbc5e.jpg)
