All three plants are 9 weeks old from seed, however I transplanted them into bigger pots in different time so that is why the size difference. The two bigger ones are being feed under mineral feeding and the smaller is in organic, receiving only water. Today 22 march is the first day I turned 12/12 and I have no idea how many weeks they will need to flower. Last week of Veg I was feeding them preparing 5 liters of solution per time, so in 5 liters I have been using 4g of Calcium Nitrate, 3g of Plant Prod, 2g of Magnesium Sulfur, PH to 6 and that is it.
