Outdoor temperature up 15C. Indoors, in grow room, 5C up on last week. Epic week of growth - lush, green canopy.
Finally understand the bouncing PH issue. Weird that no-one talks about it for the beginners. Your DWC needs daily attention. In any 24hr period, the PH rises from 5.5 to 6.5, and must be brought down again with PH Down. Thus in any one day the roots span PH=5.5-6.5 and are capable of absorbing a range of nutrients, which are absorbed into the plant at various different PH levels.
Currently feeding 13l pot with 5-10ml of Ionic Hydro Bloom daily (EC=1050-1150), 5-10ml of Liquid Oxygen daily, 1l of water daily. On Sundays, they also get 15ml of Liquid Silicon. PH adjusted daily.
No sign of buds developing yet.
