HELP!!! problem with seedling ends curling and turning yellow :/ :(

the first 3 pictures are of my pakistan valley kush I do not know what is wrong with it..
the other strain is vanilla kish and cheese bomb but they look like they are doing fine..

im growing them about 8 inches away from a t5
day temp and hum is usually around 74-77 and 38-42%
night temp and hum is about 64-67 and 30%
and the soil is happy frog they are 9 days old
help?

welcome to RIU

Not sure but it looks like nute burn rather than heat or over watering.

I'm assuming you are not adding nutes...but some soils have nutes that are a bit strong for a seedling.

your temps and RH are good.....personally I think you should get your lights closer......with CFL's I get within an inch or two max...not as sure with t5's

^^^I'd go with that^^^

The times I've had a bit of nute burn they generally ride it out, so don't stress.

yea, i did the same thing with mg time release soil. jus water whn needed. they'll do whut their suppose to. but , try to add more light. i have 5000k cfls and using mg perlite, peatmoss mix(very low nutes). working fine. i plan on adding more light myself. Grow Heavy
