this is my first grow, i started aroura indica 4 months ago. im into flower for 6 weeks. the other day i noticed what looked liked nute burn, but all i had was a bloom mix in there. there was no nitrogen in the mix and hardly any of the 0-5-4 in the water. i put my hand in the water and it was warm. i had burnt tips and the leaves were curling. i moved the 400w lights away and changed the water again. i guess my question is would this cause my problems? please help me with problem. thanx bill
