Devil Fruit/Zo Raven - 2nd grow

Had to leave town for a week, and the ladies missed me. The was someone here for daily feedings, but came back and had some yellowing on a few of the lower leaves of ZR, and to a much lesser extent the two DF. I suspect the pH might have been off a bit. Corrected that and added a little Cal Mag. Clipped the affected leaves and seems to be better now with no more yellowing in the last few days. Upped their water intake a bit to 1.75 liters/48 hours as the seemed thirsty. Despite that, all plants are progressing well into flower. The FIM on DF2 must have not broken the Apical Dominance and she is taking off to 24 inches. The other two are doing well and both about 16 inches, with multiple colas thickening up. ZR is starting to give off a distinct candy-like strawberry smell and seems to continue to be ahead of the other two.
