I've been growing outdoors off and on since the 70s but this is my first indoor grow. Everything I know about indoor growing was acquired from lurking on this site and for that I give thanks to all of you. I have 3 beautiful girls about 7-14 days from harvest but they are now showing a calcium deficiency. I'm doing an organic soil grow. My question is - should I push on through to harvest or try to treat them now? Only the leaves are affected so far - no damage to the buds. The buds are still beautiful. I would attach photos but I am an oldster and extremely low tech. Any help/guidance would be appreciated.
