DWC Purple Kush & The Purps

It's been 2 weeks since the 12/12 switch. The one larger Kush is just starting to show signs of female and nothing on the others. I have since purchased a 3x3 tent which gives me more height. I now have the light set about 18 inches higher than it was in my old tent. Leaves are still browning, crisping up and dying. Put a small dehumidifier in the tent cause the RH was getting in the 80's during lights out. Seems to be staying around 50 now. I've continued res changes every week using AN's almost complete lineup. My PPM's are at 800 with this last one. Been putting frozen water bottles in a few times a day to keep temps in the res down below 70. In the future will probably invest in a chiller/thermostat. The 2 Purps have grown noticeably bigger than the 2 Kush. They have more budding sights and will for sure yield more given that they are in fact female. Odor is very minimal, not complaining, though it is still very early.
