Hi all I'm growing a northern lights under 480watts off led.
In soil.
Water ph 6.5-6.6
I'm 3.5 weeks in to veg ever since I transplanted my fan leafs are going yellow then brown and drying up. I was veg 24 lights on. But changed to 18/6. I noticed on my hydrometer that the humidity lights out was 86 could this be the problem with the fan leaf. I'm very careful with my watering .
It's winter where I am so iv put the lights back on 24 will this help my plant il try and get pics up in a hour any help would be great.
 
Just some soil I got from the shop called grow more I used it will my last grow and it was sound. The humidity in the room is 55%. The plant was doing OK in the small pot on 24 hours light. Then I put it in 15 litre pot and changed to 18/6 but notice that rh went up to 86. So put it back on 24 on
 
I don't think humidity or the change in light schedule would cause this. I'm not sure what is going on. How oftem do you water the plant and how much.
 
few possible issues

-Humidity is way to high at 86%
-Switching the pot and the light cycle at the same time is doubling up the potential stress
-Pre nuted Soil can easily burn plants
-People usually tend to over water ,are you allowing the soil to completely dry out ?
-What is the PH of your soil


I don't see the marks you are talking about in the second picture but I would guess the other issue is one of or a combo of the things listed above
 
I water every three days I have a soil tester that tells me the soil is dry when it's on the red. Il take a picture of the whole plant not under the lights. I also have two fans in there one on top of plant and the other below.
