I looked over your diary and im not seeing any signs of white or light burn on the seedlings??
and your 150W led would have a hard time burning them at 27inches way from the seedling I find.
Your can upload photos to the question you ask to pin point any of the things your asking about.
The little white tips coming out of the seeds in germination are its tap root and that is 100% normal.
Light burn on plants tends to cause the leaves to turn up and get crispy. They can also be albino/bleached if they get to close to the light but then tend to happen to bud sites that stretch high not seedlings.
One thing that looks a bit concerning is how wet the medium is, be careful not to over water them. They will get weird deformed leaves as a seedling and .yellow out on new growth.
If you want to ask a new question with this extra info if you think something is still wrong we can better address your question.
Good Luck and Happy Growing.
Good stuff, really bushy. It says i water a gallon every 24 hours but there isnt one for a week. Normally I water one gallon per week and if they droop a little before then I water about a liter or so and make sure it gets a gallon on the day it was supposed to with the needed nutrients. I have a fabric pot so everything should be ok
If you want to confirm its nutrient burn or lockout all you need to do is keep an eye on your TDS numbers you're feeding with.
If you don't have a TDS pen I recommend getting one. always good to know the concentration of the solution your giving them.
I see your going in a soil coir mix. I would have bumped my PH up to 6.4-6.5 but if its working for you keep it where its at.
If you keep running into more problems that might be an area to look at.
Remember autos do not feed as heavy as photoperiods. and yours is very green. Maybe to much N.
Love this link. its a great tool, use it as a reference for feeding and listen to other who use the GH trio lineup for feeding.

The yellowing of the tips is also the very beginning signs of potassium deficiency.
you have some flora grow and micro and they have a nice amount of potassium, doubt this is the problem.
Try and get a TDS pen.
Best Of Luck!
Just phed water this week. Defoiliated the bottom which recieves no light what soever. I have changed the light schedule from 24/0 to 18/6 because of your feedbacks.
I think my plant has something wrong with it. The leaves seem be like as if something ate it. and the tips of the weed leaves shrivel up dried but the entirety of it seems ok...

The funny leaf is nothing to worry about, no plant will ever have 100% perfect leaves, 100% of the time.
If it were insects, you would actually be able to determine "bite" marks.
The tip burning is from too much nitrogen, autos really only require half strength nutrients in my experience.
Since you are basically growing in soil, a schedule of plain water/ plain water/ feed, so that you are feeding every 10-12 days seems to work best too.
Congratulations on going to 18/6, cannabis does need sleep to function properly!
Hope this helps. Organoman.
No you do not have nute burn. Actually plant was wanting more potassium, and phosphorus so it kinda started fading the plant. Nute burn your leaf tips turn brown, and curl up and in sharply. Looks good enjoy🌱
Chopped earlier than expected. I thought it was finished., I dried for a couple of days until the branches snapped without bending. Usually the good old stuff you can find from websites concerning this.
