AsNoriuanswered grow question 6h ago Simple math for good grower is 1W =1g, so you are in 80g area with such light.
Dont do big plant ( aka dont veg long if its photoperiod).
If its your first grow, just let plant do its thing, forget about all trainings in veg stage.
Depending on plant size, on week 3 of flower i would recomend to clean bottoms a bit .
Ph, watering regime, right food proportions and humidity with temps is all you need to care.
Have fun !
