Hello I've got 2 big Buddha cheese auto's that haven't started flowering at all. They're at week 7 now and the rest are all in full bloom. They all look healthy inuff to me so I'm sure it's not stress related. Anyway I no the obvious thing might be to flip the lights to 12-12 but if that works and they start flowering would it be better to leave it on 12-12 for the rest of the grow or put the hours back up to 20-4? The thing is they're meant to be auto's and they need longer hours of light to produce the yields so I don't no what to do. Thanks for any info at all.
