im using organic miracle grow soil with no nutes added....im simply using tapwater thats been sitting in a empty milk jug for a day or two...

and its weird that the tip burn is only happening to one plant...it definitly isnt rootbound i just transplanted it a few days ago but it was previously rootbound...

so you got any advice on wat i should use? i wanna start feeding em but i have no clue how to go about this....thanks
