Okay folks this is my first time inside grow and I'm still coming up to speed. Reading a lot on inside growing anyway I'm pretty sure this is nute burn I think. I'm in a five gallon bucket self watering with my reservoir below. If this is nute burn if I just flush out the reservoir will that be enough or do you think I need to flush out my grow medium? The problem is not bad now I just want to get ahead of it before it gets worse. She's a photo.Thanks for any good advice.
