i wouldnt call white rhino exotic, its pretty damn common it you ask me. but other than that i agree with hawaiinsolja. if you just topped your plant, you just cut off the most productive part. if you dont wait for it to grow into 2 more tops you will be sacrificing your top buds, not very appealing to me. i would wait at least 2-3 wks as long as your not getting to tall for your area. remember your plants will strech up to 1/3 taller when you switch to flowering so plan ahead. best of luck!!
