The first 2 serrated leaves on each of my four plants are turning yellow..but new growth looks ok..What could this Be? It happened when I put them under my 250w dual spec when they was 8 days old..First thought it was heat related so I moved my light higher..but the leaves havnt got any better..but it hasn't spread to other leaves..really confused what it could be..I've got carbon filter/inline fan set up with 2 mini fans..the light is now on 400w because the plants are older an the temp average is 26-27c an humidity between 45-60%. The yellowing looks a little worse than what you can see in the last pic

cheers for the advice mate..I've raised the light up to 140cm which is right at top of my tent.. I only lowered it too 18inch because I've been told by that many people if it's too hot when you do the hand test then it's too hot for the plant..an I put my hand just above the canopy for 2mins an it wasn't the slightest bit hot so I thought it would be fine with them being 16 days old
Cheers mate I think your right..it's definatly not the heat so it's gotta be intensity.. I put them under 250w at 15inch when they was about 8 days old an that's when the first 2 true leaves started yellowing. Just altered it to 3ft so I'm gonna leave it like that till they get abit bigger..rather Be safe than sorry!
