Changing light type late flower?

[ocgreen]

I have a tent with 260w 3500k QB & 315W CMH. I want to take out the QB and replace with another CMH.

Will the plant directly under LED get stressed from change in light type?

Well, I vote for a 600W HPS for the rest of the flower. And all of them will be happy.

No, It won’t stress her too much...but your yields will go down if nothing else changes.

Don't risk it, it doesn't take a lot to force a male flower and seed your whole stash.

Thanks all. I understand some may prefer HPS lights but this post was all about leveraging what I have already.

After weighing various options, I decided to leave lighting as-is in 4x4 to avoid stress.

Basically the extra CMH (which I was going to swap with QB) will go to where I wanted to put the QB until after the 4x4 plants are done flowering.
