For a 1000watt...well, I'll just say next time I think you should get bigger pots or at least better soil. Also how far away from the tops are the lights? And also 90 days seems loooong enough lol especially if the time of harvest was given as 60-65 days. And you should have been stopped giving them nutrients. Honestly the leaves may be turning yellow because maybe they are dying, they've been living long enough lol. And honestly milky trichomes are fine. More than fine. You'll enjoy it

Also what is the name of the strain that you got from Dr. Chronic? I want to see what it looks like.
