soil burning seedlings.

Hey guys. I got fast bud automatic and Nirvana auto Northern lights.
Im using some local soil for palm trees, prenuted with ph 6.5-7.2, mixed with 25% perlite
The NL has 4 leaves already with some yellowing on tips.
FB got the "stem" out of soil and the 2 roundy leaves already seems to be yellowish.
Is it cause my soil too hot for my small babies?
Also, I got some soil in my backyard, from compost. We throw banana, potatoe, cucumber, vegetable peels and all that sort of things. Under thetop layer I can find some black dirt there. Is it useable or it could have some diseases and weeds etc.?
any input aprecitated, stay high

the thought of using home compost gives me shivers. i prefer nice sterilized germ/bug free stuff.

I thought already, but wasnt sure. So, what can I do to not let hot soil burn my seedlings?

could it be caused by overwatering, i read it on other forums

Overwatering and overfeeding are the main reasons that seedlings fail to thrive, along with light. Put up some pics if you want a valid diagnosis. I use "home compost". If it is properly composted and no diseased plants were used in the pile, then it should be good. I always use seedling starter soil for my seedlings, so no guesswork.
