Great week, first of all this girl is growing like crazy, guess that's why it's called weed, literally can't move my lights away from her fast enough, grew easy 5" in a week. Huge leaves hanging off it drinking all the light, stem is so thick already, I think she could be a big girl, probably too big for my set up.
Growing in soil, so still no need for nutrients, watering her plenty, sucking it up rapidly.
Problems: nitrogen, leaves curling and clawing a bit, should sort itself out with time. Also, due to her rapid growth she got burnt a bit, but nothing serious.
Great week of growing.
@HighTV, cheers for the comment, I wasn't sure, it seems to be reserved to the top few leaves, and up until i took these pics they were slightly above the lights, which I've now remedied, and the light is now well and truly above the plant. So I'll give her a few days and see what's happening.
