Back from vacation and will start giving each plant 1L of water every 2 or 3 days. Probably start with some nutrients this week, 25% of the total solution with 2/3 base and 1/3 bloom solution every second watering to see what happens.
08/05 - Topped the Blueberry plant at the 3rd true node. Will do the same for the Glueberry as soon as she grows a bit taller.
