I'm really confused at the moment.
My seedlings started off great when germinated and started off in 1 inch RW cubes.
Since transplanting to a larger 3 inch rockwool cube I've had problems with the leaves curling downwards. I thought at first that perhaps this was due to overwatering so I'm letting the cubes dry out for a few days and they still look the same. I did presoak the rockwool and stabalizhed the PH to 5.5.
The tips also look slightly burnt but new leaf growth is still ok although not as fast as I was hoping for.
Temperatures are fluctuating between 76 and 85 F and humidity is about 30 - 40 %. The PH of the water I was feeding has been between 5.4 - 5.7 and I've now increased this slightly to 6 - 6.1 based on the information that I found. The PPM of the feed was a bit high when I transplanted the seedlings into the larger cubes at 550 - 600 but I'm using tap water and quarter strength nutrient solution.
Also it's been 5 days and I havn't seen any roots grow out of the cubes yet. Is this normal?
