Hi all, I'm ten days into my first grow. I'm growing Think Different under 300w led, in Canna Terra Pro Plus. I'm wondering when I'm supposed to start giving my plant nutrients? Some people say that Pro Plus has enough nutrients to last a few weeks, other people seem to start giving their plants a weak dose (1/4, 1/6) at around ten days. Just wonder what people here think? Plant looks healthy enough, so I don't really want to feed it unnecessarily. Thoughts?
