AEROGARDEN DAY67 FROM SEED week 4 flowering

The ladies are doing good other than the addition of fungus gnats and larvae tot her roots. I have ordered a natural bacteria that eats the larvae, and kills off the flies that lay eggs in the fungus that surrounds the stems in my aerogardens' medium. We have slight leaf curling due to the larvae and flies. We also have weird root growth from one of our clones. The pictures are Grace (sativa) Delilah (indica) and Nickie (sativa) I FIGURE 3 -4 MORE WEEKS AND IT WILL BE TIME TO HARVEST!!!
Depending on tricomes. delialah, and grace are covered with crystals.
