Indoor When to switch to 2700k lights

[Stin121]

I am sure this is here somewhere, but alas I am on my phone and can't search that well.

When is the best time to swap my 6500k lights for my 2700k lights? Both of my plants are now showing their sex. They both are 30 days old. I know I read somewhere that you can leave the 6500k the whole time but I only have 6 of those and 12 5000k that I have been using. I want to switch so they have the most of the proper light to get the most bang for my buck.

BTW they are northern lights autos.

Wait until vertical growth starts to slow, around week 5-6. When you switch the lights also switch from veg to bloom nutrients.

Ok great thanks. I was going to do one more week of veg nutes then switch. So that would be around 5 weeks.

I'll watch the growth and adjust accordingly.

Ok it's been awhile. So all of the lower fan leaves on both plants turned yellow almost overnight. I guessed nitrogen or lack there of was the cause. I uped the nutes and watered it. It looked much better the next day. I'll confess I used wire to LST the plants at first but finally switched over to green gardening twine. I also trimmed off some fan leaves that were blocking bud sites.

Here are pics from last night. Day 36
