HELP! Newbie Help!!!

[Swizzler]

Hey everyone Nate here,
Started have some leaf issues, needed help diagnosing. This is my first indoor grow started from seed using Crop King Fem seeds. Over all pretty pleased with the seeds. Currently at 3 weeks Old.
Im leaning towards overwatering +nutrient burn.
I wanted to push my experience.. currently growing 4strains.
Gilato
Blue Haze
Amnisha Lemon
Banana Punch
I'm using 1000w Led.
Temp 23-25C
Humidity fluctuates 45 50%
Ph 5.8-6.8
Media Coco coir/ worm castings/ perlight
I had to transplant early to help reduce from stretching .And may have started giving nutrients a week or so too soon. I Know newbie growers so impatient lol.

Last week I started noticing curled down leaves with another plant with curled up edges. I have also noticed cupping of the leave and shiny look. Is this light burn?
I have since stoped all nutrients and reduced feeding with distilled water.Some have started to recover but my Gilato is now showing burned tips and edges.
Any suggestions would be awesome. Happy 420

Have you checked the ph at the root zone? Read up on copper deficiency. Your girls do look like there's some heat stress going on as well. Your catching issues early and if fixed soon you should still have a great harvest. Good luck Nate.
