I have 2 autos going a gorilla glue and a crystal meth both from 2 fast 4 buds via seedsman they hit 7 weeks from germination this past Friday the crystal meth is flowering beautifully but the gorilla glue is still stretching and in preflower throwing a few hairs but not really, do I need to switch to 12/12 for a few days to trigger flowering then switch back to 18/6 or just keep waiting on it to start itself
