<span class="link_user">@CocoGROW</span>, hey man. Check at the top of the page just underneath the prizes pic, should have a join button in green. If you've got a completed diary and you meet the requirements you should be able to join no probs.
@@Athos, thanks for answering. Yeah, I wont be feeding untill a month or like u mentioned unless deficiencies start showing. Is there another better ratio for fertilizers that you recomend? For example like a 5-5-5 or or 2-4-2?
