I'd first say you root bound. Most people start in a 4-6" pot and re-pot before a month has passed, into a 2-3 Gallon pot. I posted pics of all three of my first plants at 30 days to compare. (BTW they were JUST re-potted before the pics)

As for your dots, could be nutes, PH, or if indoors it might be Ozone damage.

Unfortunately, your diagnosis may not be applicable; they were transferred into their 4" pots 2 weeks ago.

I didn't even try to diagnose the spots. ;)

What I DID do was give you a link to try and figure if out for yourself.

PLUS,.. I pointed out that you SHOULD be a LOT bigger at 30+ days.:thumbsup:

did you fill that bit in right or is it a typo? 7 hours of light per day?

Vancefish gave you as much help as he could with the information you provided. You will probably get more help if you fill in the cannabis.com troubleshooting form. It's easy to misdiagnose a problem without the right information.
