Seedlings showing signs of what I believe must be nute burn.
- propogated via the paper towel method with no issues, all germinated.
- transplanted into rockwool cubes. I'll never use rockwool for seeds again. Very hard to get the curly roots in them, and they hold too much water, not easy to control.
- soaked rockwool in 400 ppm nute solution.
- under very low intensity lighting.
The picture isn't great but one of the baby leaves is dark brown at the tip. This is like that for about 6 of the 30 some seedlings. And one of them both leaves are burnt and it is clearly dead.
The rockwool cubes are not soaking wet, they are lightly moist. I've been misting the leaves with filtered and ph'd water. I'm wondering if I should flush the cubes with water, but I feel like that might be too much for the delicate roots.
Any advice on how to proceed is appreciated.
