I'd say you should cut off for a month at least, and stick to weed for that time. However keep the weed smoking to a minumum and get your brain fully reset into normal mode. Then when and if you go back to hallucinogen's, do them in very low doses (like a single cap for shrooms) and see how things are. you may actually enjoy the lighter trip a lot more if you learn to mentally flow with it and not depend on the substance 100% for the good feelings.
