Thanks,Ya they are looking ok, some still have a slight mag deficiencies but starting to pass I think, the new growth is looking good.
I'm not going to have any donkey kongs like you do but I never do.
My ppfd was only around 3-400 so thinking I should start pumping up the ppfd.
What ranges you shoot for when in different parts of flower?
It's hard to say but usually ~500ppfd once they're established in veg mode and by the time the stretch is over they're usually sitting around 700-1000ppfd. What I do is set my lights to 100% at a distance that gives me around 5-600umol in 18/6 and then once I start 12/12 I just let the plants stretch into the light and monitor the par as I go.
I think my next run I'm going to do a test and see how much light I can push seedlings all the way through veg, Bugbee says you can push young plants extremely hard as long as you've got all the variables in check.
