Ideally you should use your grain as soon as you mill it - like fresh coffee. However, in practice, if the cracked grain has been relatively cool and dry it will be fine for 3-4 weeks. Will it have "lost something"? Perhaps. But I doubt it would make as big of a difference as yeast health or ferm temp control. In the grand scheme of things, it will be fine.
Hell - that LME that you used to use probably hung around for MONTHS in that drum at the LHBS. It has to be better than that.
