150 watts of MH, 180 watts of CFL. Bubbleponics nutes.

Could this be due to PH or over nuting? BTW I never tested the PH of my water but tomorrow i am getting a test kit and ph up/down.

if it's only on the first leaves i wouldn't worry too much...i had that same thing and the leaves didn't grow and eventually just died..i cut them off and it is growing like a bastard and i haven't had anything like that with any of the other leaves...the rest of your leaves look nice...just keep an eye out...and to be honest i can't really pin point what causes it..but yeah, if it doesn't spred..it should be all set

These brown spots have started on the very tips of my top newer leaves.

WHat could be the cause? heat stress?

Here are pics. The water droplets were just added because i sprayed the leaves. I havent done this before so this is not causing the burns. It is spreading to all 3 plants

Take it easy on the nutes this early in the seedlings life. Young plants don't handle nutes very well. I would switch to plain water until it's about 2 weeks old, then start adding nutes at 25% strength. You can gradually increase the nute content from there.
