Are they from bomb seeds as well? That seems to be similar to the problem I've had, it seems like my most progressed plant had a strong auto gene but my other 3 auto plants seem to have more of a strong photo gene and only started flowering when I knocked the lights down from 24 hours to 20 hours on 4 off whereas my most progressed plant flowered with 24 hours of light I don't want to have my lights off any longer than 4 hours as I have a photo plant in with them that I want cuttings off. I've been quietly following your grow, I must say I do like your diy set up it looks like the dogs bollocks.
