Time to switch!

[Nedhead]

Hi All,

I have two on the grow. One auto and one non auto. I think they are both pretty healthy and I am about to switch to 12/12 for the non auto and have a couple questions for the fine crowd at 420.

When I switch to 12/12 should I do it at the start of a new day? IE. let the 18/6 run it’s course today and then after 6 hours of nighttime switch to 12/12 or can I switch in the middle of the day?

When non auto starts to flower should I start blooming nutes then at 1/4 - 1/2 dose? Full dose? Should I wait until she has been flowering for a week first?

In the pic the one in the left is a Northern Lights auto and on the right is Blue Cookies non-auto. Both are about 16” tall.

It doesn't matter overmuch - but remember, it's not the hours of light that matter, it's the hours of uninterrupted darkness. So it doesn't count until that first 12 hours of no light.
