Sour Sundae - Indoor - SF4000

Im getting really close to flowering now, I am waiting until my AC infinity exchaust fan/carbon filter come in and my transfer pump for my run-off trays and then they will flower. As you can see, on one of the plants the stems has a piece of mold where I supercropped. I battled this with a diluted bleach solution, this is also a reason why I have not yet put the plants into flowering. When the carbon filter and exhaust fan have arrived + when the the mold is gone, I willl start flowering the plants. The SF4000 is turned on 80% now, I am still slowly turning it up. I have lollipopped them but I was a little to early...
