I said I do not understand how reducing the light intensity from 10 to 5 by turning the light down then lowering the light to bring it back up to 10 changes things. If I disagreed I would have said "I disagreed..." rather than say, "I am unsure...".
I have seedlings a few days older than those right now and they stretched more than I want to see but they just popped out of the ground and shot up in a day. I lowered the light but the mature leaves started praying so I raised the light again.
