Burnt tips on seedlings

Please advise, my seedling has the tips getting yellow! Soil ph is 5.8 ( the other seedling is 6.4 looks fine) led light was 8” above at 30%. Is it the PH or light?

Also is it small for a week old?


You want your ph to be 6.5 when watering soil, that would explain why your other plant at ph6.4 looks better.

I would get your ph in order and then re-evaluate, for a week old she looks to be healthy and not stretching much.

A decent ph meter is your best friend especially when it comes to troubleshooting, improper ph stops the plant from uptaking nutrients and this leads to a whole buttload of issues down the road like stunted growth
