Cleaned reservoir and filled it only with 2 gallons of ph'd water. Trying to get the roots to reach the bottom. I made a mistake before and used too much water. Hopefully me fixing that mistake will help the plants grow more. Still growing rapidly. doubled in size. Upped the DLI to 30. PPFD is at 470. Plan on starting LST next week. Officially 21 days old at this point.
