Well it seems this girl turned out to be an auto! Unstable genetics or mix up of seeds? She was moved into flowering tent with the rest of the veging FF plants, the only 1 with pistils where she continued to flower growing nice dense buds how ever 3 weeks into flower & the rest of the FF plants weren't even getting pistils??? On inspection I found 1 of the lights had been on continuesly as the switch on the timer wasn't on the clock setting but switched to being on constantly!!! Proves she's definitely an auto!
