10/Mar/2017:
For some days I'm not adding new pictures as I'm changing my cellphone. Just look the photo with the Sweet Cheese emerging from the soil. The girls are looking awesome, maybe shorter for 2 full weeks of vegetation but appearing a new leaf every day.
Some tech data I'm trying to record for each week:
Sweet Cheese recently germinated #2: pH 5.8 --- EC 1610 PPM - 3260 µS/cm
The others:
Sweet Cheese #1: pH 5.8 --- EC 1720 ppm - 3430 µS/cm
Sweet Skunk #1: pH 5.9 --- EC 1580 ppm - 3175 µS/cm
Sweet Skunk #2: pH 5.95 --- EC 1290 ppm - 2580 µS/cm
The EC is decreasing but also the pH. I think maybe I've to add some alcaline solution to the water to increase the pH, but right now I'm more worry about the EC as I don't want to they have any blockage on the nutrient intake.
