Green Apple Juice Auto

Too much stress,really cold environment,some times with the grow light off the temperature is around 13/15C and the air goes direct to this plant because the fan is close enough,the Plant doesn’t give up and has some over feed too,idk why but I’m using nutrients after 15/20 days and half of dosage that BioBizz says and I still have over feed a little bit and nutrient lockout maybe because I’m using some Bio Molasses Blackstrap but if I’m using molasses I’m not using bio grow and I’m using like 3/4ml per L.The LST is because the plant got really tall that the grow lamp couldn’t go higher because of my grow tent size and I needed to break the top cola.
