Please Help...Wilting leaves wk 5 Flowering

Please can anyone help me.... after 4 weeks of flowering under warm red fluro lights in a cupboard everything was going tops.... unfortunately i was required to move my plant to a diff. cupboard due to the in-laws visiting. The plant has now started to wilt and the leaves are curling. I have watered every 3-4 days.... neither water nor letting them dry out has seemed to effect the curled and droopy leaves. Its now just going into week 6. Can anyone please save my baby... i'm so close to harvest but all could be ruined..

Well when there's a deficiency of nutrients there is usually more than one sign, and after studying the pic's I can't see much wrong.

Yet, gathering that you are not panicking over nothing and the over-all plant looks much worse than the pic's would have you believe, then we could be witnessing either the beginnings of a nute def'... or there could be a temp's problem... or a circulation problem... or a pH problem.

Cheers.... maybe its just circulation cause nothing else i have changed but the cupboard which is a bit smaller. I'll try increasing this and see how I go. Thanks heaps.
