Was other factors are you referring to if you don’t mind me asking?
too many to state them all, but leaves may hang from osmotic root pressure, turgor pressure, too low transpiration.. and all this stuff can be influenced yet by just a bunch of other stuff, like ambient temps, rH, soil pH, soil EC etc... plants also need some time to adapt to changes... even if you just move your pot around and place the plant at another angle to your grow lights it may have to adapt anew... so for best growth, just try to introduce as little as changes as possible, or, rather step-by-step
