Droopy leaves

Yeah I am in Bio Bizz all mix soil, bio bizz nutrient like, 420W light, and OH is 6.5 going in always, nutrients or not, I think like said above it could have been either under or over watering, and plus twice I didn’t water until I had run off, so I’m thinking maybe the soil didn’t drain as well as it should have so I gently made a few more holes in bottom of pot, I was watering every 2/3 days whenever pot felt light or too inch of soil felt dry

does this cycle start near end of day or get worse as day (*whatever period when lights are on) goes on? might be too much light. this can happen throughout day, normally. leaves rise and fall a bit. if extreme, i'd look into some other things like DLI and guesstimate what you are providing etc etc.. to make a more informed decision on the light situation. if you just flipped from vege to bloom and providing 150 percent more light (relative to 18 -> 12 hours lights on reduction), the plant may need a little transition before blasting them with that much more light over fewer hours to maintain same level of energy given per day as before. the hours change, but the plant can still only accept so much energy per day relative to some environmental factors. does it happen only afer watering? this could be fixed next tme with a little more perlite or similar addition to soil to improve drainage. i wouldn't do anything too drastic. maybe raise light 2 inches? while there's not much info given, hopefully something here is a parallel and useful

Maybe @Growdiaries know the awnser?
