Just took another foot of growth off the tops. Leaves were looking yellow so gave them some Epsom salts. No green veins with the yellowing so didn't think it was a nitrogen defishancy. I think it is defishancy in magnesium and calcium. Gave the girls there weekly tea and had to increase the water to 3 gallons every other day. The girls let me know when they are thirsty. Weather is in the 90's and 110 in the greenhouse. Looking forward to start of flowering in next couple of weeks.
