transplanting and switching different lights question

Hello, I am about to flower my plants.First I want to transplant my 3gal pot to a 7 gal but I will also be using a HID for flower. I used a LED with CFLs for veg(CFLs most of its life).
My question is should i have my plants under HID before I transplant.
Also do these plants look fine to you guys

Your plants look great. I would not switch lights and transplant at the same time. I transplant first then wait a week to 10 day to make sure there is no transplant shock and then go under HID. And when you start keep the HID high up and lower it over a week or so. You should be fine. Good luck
