Slight leaf curl

[4d-Rock]

I run my qb at 90% all the time. I start my seedlings at 30 inches or so let them grow into them. If i think they can take more i raise the pots. Check a few hours later for curl. If very slight ridge curl i let them be usually they adjust.
Only way to know is increase and observe.

On my current grow (in sig) I mounted 2 DIY Cobs at the top of my tent which is ~34" from the seedlings. I have been letting them grow up while also LSTing so it doesn't get too out of hand. Things are going quite well so far and I just recently turned on the 135W QB (always runs 100%, no dimmer). The plants are just starting to pre-flower so I hope this is the right timing to increase intensity. This setup and sequencing of light is new to me so it's all one big experiment.
