8/26 - Plants are now on a 12/12 cycle, since they are in a tent with my other photoperiod plants that were ready to switch to flower. I am sure that it can lead to slightly stretchy plants, or just overall less developed plants, but as autos, I'm not too worried long term about it.
8/28 - Watered today (after photos), with the 3g pot getting about 1.5L and the 5g pot getting 2L of water. My biggest/only complaint about the medium used (Detroit Nutrient Company Living Soil) is that it dries out quickly, and appears to be extremely hydrophobic, making watering a bit tougher.
8/31 - Appears both plants are showing preflowers. Since this is my first time growing an auto, as well as going with 12/12, I don't know what to expect. Both plants are right around the 6" tall mark, so as I said, I don't know what to expect, but I guess time will tell!
I'm currently growing this too and some of my fan leaves are doing the same thing, maybe it's just a genetics thing after all or they just love there nutes! Glad to see I'm not the only one with this problem though.
