So i'm having a wee issue and not sure if its a major problem but it seems they are happy when the lights first turn on for the first 7hours they seem to be okay, i check them in the morning when i wake up a couple hours before lights off and 2 of them are sagging.
400w MH @ 18 inches away.
Temp is around 77-85 lights on and 60-65 lights off.
Humidity is around 40 on and 70 off.
I have 2 small fans running between the lights and the plants (the leaves dance a little bit with this).
Also have 180cfm fan with filter etc running with passive intake so plenty of air exchange.
I did lower my lights to 14 inches the other day and they showed signs of heat stress so i raised them back to 18 which they were originally at.
First picture shows just as the lights come on...as you can see the plant on the left doesn't get affected at all, it's mainly the middle and right hand plant.
