Started watering 4 L per 5 gallon every 3 to 7 days instead of one liter every day or two.
Looks like she's got another few weeks to go.
Can't wait to get these girls out of here because the sweet creams taking over the room getting too damn big.
@Drako921,that sux, i kno i wont leave it on more than a few days anymore without intervening.
Lesson learned.
Lol. She did catch up nicely though, surprisingly.
