If you think you are to lose, or to strong with the lights, come back to the plant
they should always have lovely lushgreen leaves, wich are quite relaxed
and the internodial diatance should be at least bewtween 1,5 and 3 cm
if the internodes are closer, and they are growing " ducking under the light" you light is to strong- the distance is to far
if they are growing very longish / lanky with wide internodes, if flowers dont fill out well after 3 weeks- you light is to weak
but most times growers tend to blast alot of light on the girls
means you see much lighter topleaves than the next layer, ( lightburn)
after few runs you know the distance- just look at the plant
numbers in dimming and distance say nothing- because the srains grow super different
