I reckon the runty one will end up the queen of the bunch, Mary Jane can be odd in that way. I remember years ago an ex of mines cousin was attempting to grow and i use attempt loosely. He said he did 2 weeks on 24hr under some silly amount of 1000w hps bulbs was like 3 or 4 a plant and got paranoid and turned it all off for a week n a bit then turned lights on for 24h for few days then darkness for a bit and this went on and he showed me his grow and it was fuckin mental. The plants where all Frankensteined but one a little tiny ak47 which was about 9inches tall hat one finger leaved on and really frosty lil buds. I gave him £10 for plant and a light, didnt need the light as had my own crop up at the time just he didn't need to know lol. I put it in with my plants in flower for 5 days or so chopped it cured it for bout 3 months and it was amazing only got 3g but it was amazing (probably not that good but if you would of seen the plant you would agree)
