my first clones

[demcc3]

Hi everyone. These are my first two clones.....ever. yah I know..they don't look too healthy with the browning of the tips but more of my concern is the speckled/irregular appearance of a few leaves in both pictures. I'm hope this isnt indication of an infestation!

Thanks

Need a close up of that. You've got nute burn so if it's a nute deficiency it will be pH lockout.
I hope it's not pests
