Advanced seeds grow

Hey folks, how are you this week ? We got some growth this week, nothing too fancy yet, i watered them with nutrients for the first time on 29/08. I watered them with half the recommended dose of nutrients, i used 1ml of bio grow per liter of water, i watered 100ml of water with nutrients for witch plant. They sucked that water pretty quickly and at 01/09 they where pretty thirsty once again. Today (02/09) i watered them with 100ml of pure water with no nutrients, and a PH of 6.2. Im keeping the PH between 6.2 and 6.4. They got some yellowing leaves on the bottom, but only that first serrated leave. See you next week guys, keep growing.
