Yo, that's not lockout, that's hunger. They begging for food

I've not read through the thread but I would say your soil ain't living atm and they're not getting the required nutrients. If they were locked out they would look deep green and have burnt tips. Turning the lights up is like putting your foot on the gas when the car is running on empty.
You may have to bite the bullet and give them some bottled food that is directly available. Even then you may not see an improvement now as they're quite a way into the flowering cycle.
Don't get disheartened, it's a learning process. Every grower out there has been through the same types of issues before they had success.
Those who can make you believe absurdities can make you commit atrocities.
