i have several plants w/varying genetics.we have had several days of rain and they all started to bloom today.my bro said stop nitrogen.i read only slightly reduce..for 2-3 weeks which is correct???? also i have read several times to stop nutes 7-10 or 10-14 days before harvest to cleanse plants. again he disagrees and said he read on this site to feed until chop.?????? which is correct?best book on growing??THANKS!!last query-the pineapple chunks were supposed to finish mid september because of strong indica gens. according to single seed info. as i said, just starting to flower today,will be done mid- oct. why??
