Auto White Widow 1st Time Grower

So after 94 days Emilia, Ella and Sadie have been cut down. None of these 3 plants produced much more then lessons to be learnt. I’m contributing the lack of yield to a couple key failures.......first is the under powered light for first month and a half. Second would be very early Low stress training. But the biggest failure I think I had this first time growing was my rush to flush, made the mistake of completely flushing soil to till it was the same ppm as the tap water used to flush. Leaving no flowering nutrients available to the flowers at an important time. Latest mistake would be cutting them down befor fan leaves all browned. Now with that said I knew when cutting them down they were not going to do anything more then they had already done. They were at this point just wasting space in the tent and slowing down the next round of plants. Delilah is the last plant standing at this point so she has been moved from an indoor tent to the back enclosed patio. Guessing she will keep going for another month or so. Another guess would be that this last of 4 plants will produce more then all 3 of the others combined.
