Hi mate, nice to see it going. For that one looking kind a down, stop watering few days (3-5) until you get more air into the soil or maybe you allready have a root bound due to higher light mount because plants like to push down like they push up so transfer to bigger pot would resolve your problem put it in 20L airpot/textile and before flowering put it in 40L textile/airpot and you will pull 100g min. dry top qual. buds from each (don't know how long you veg. but in 6-7 weeks of veg + 7-9weeks of flower you must get 100g. per plant min.)
