Thanks Dutch

That is what I thought but my lamp is at least 18 to 20 inches above the canopy, I turn and or rearange the girls under the light every 1 or 2 days.
I also test the temp above the canopy by placing my hand about 4 inches above the plants and it feels OK.
As I said it's only the 4 Skunk that are affected, the others are fine.

All the other plants look great (in fact so do Rating: 5
