I had some clones planted in peat/coco in 750ml pots under T5 at about 230 ppfd pfd. Transplanted them to 5 gallon buckets and moved them to the flower room where I have HLG scorpion diablo 650 LEDs. I bumped the light to around 250 ppfd and was going to slowly increas to 350-400 to veg them out. I noticed some of the plants showed stress after about 16 hours (I do 24/0 light for veg). So I backed the ppfd down to 130-140 at the max light points. They seemed to bounce back a bit already and its only been about 10 hours since the change.
So is it that the light from the LED is so efficient and the plant uses so much of the spectrum that I should actually be lowering my ppfd a bit initialy to transition them or is there something else going on here. I kept temp and humidity about the same as it was under the T5s
65% humidity 75 degrees F and will taper the humidity down in the coming weeks and temperature up.
But I was on the lookout for transition stress as this happend on my last round aswell and it just slowed my veg time down from having to recover from whatever stress they were experiencing. Mostly yellowing top leaves curling down big time in some of the plants.
So my main thought/ question is should I optimally be dialing my ppfd down a tad coming into the LEDs from the ppfd that I was at on T5's?
Any input appreciated.
