Seeing some top bud leaf discoloration
Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity

Light or nutrient burn?
Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?

So Dark Devil is showing some signs of N toxicity as far as I can tell. I have lowered her feeding to 1/3 of recommended, and then she just got plain pH water. When should I introduce nutes again and how much? Also should I flush her thoroughly beforehand?

Is this a deficiency? If so which deficiency? If not, what else could be causing this?
Any idea what could be causing this to happen to these leaves? The tips are becoming pretty brittle.

Yellowing leaf tips
I have slight yellowing tint on the edge of a few leaves closer to the top of the plant. I am using 1/4 strength big bud and 1/4 strength bud candy. My light was about 18 inches from the canopy so I raised it to about 26-28 inches above canopy. Do you think this is light burn?

Brown Tips on Leaves
I've noticed some brown tips starting to show on my autoflower plant -- the Auto Blue on my page. I personally believe it's from overwatering barely, though I have solid air circulation and try not to water until the soil is truly dry. Any help would be appreciated!
