does this look ok?.......its my first and is 1 week into flowering and 70cm...a couple of leaves have yellowed tips and a couple of yellow spots..but only a couple......

I recon its probably heat burn as I have it under a 600wat with no cool tube and have adusted it accordingly..but Im not absolutely sure.

Also looking at the photo, would anyone give me estimate of how much it will yeild?...thanks
