Check mark.. Should mention I transplanted into the bigger rockwool cubes 4 days ago.. Is it possible I broke a small portion of the roots? If this helps:

Rockwool retains water, if the cubes are sitting in 1" of water, they may as well be sat in 5". They are drowning. IMHO..... No water in ya table, hand water every 3-4 days until roots break through rockwool. Put your 4" cubes ontop of a secondary medium (hydroton or coir) and then flood your table but not let the flood level hit the cubes. Your roots will be doing the drinking while upper roots in rockwool will be sucking up o2, more importantly not drowning.

I've drained all the water this morning.. I'll check the plants when I get home in 2hrs.. That will give it 11hrs with wet rockwool ..no sitting water...

I read a forum about a tabbacco disease that has symptoms like this, curved leaves with yellow tips and random brow spots

I agree with the drowning though. The damage is done, just look at new growth not them old leaves.
