OH GOOD LORD do you have thrips but good.
Yup that plant is super rootbound and most of your stress problems are related to that, and your high pH.
There's a great agway product, I'm attaching a pic, that is pH PERFECT for cannabis. Mix it with 30-40% perlite.
You also need to pick up some bug spray. Since you are in veg, you can use the bonide rotenone with pyrethrins product, but do it NOW because the thrips are outta fuckin CONTROL. Wow.
