Really Worried about little sprout?Help!

I have a picture included of what my little sproutling looks like:unhealthy!its stem is purple and its leaves seem weak and dry...Im keeping up a temp of 70-75 F but that requires my heater.aaand the heater dries up the air in my room(im growing in a grow box in my room) so the humidity is hard to keep up.I don't have a humidifier right now, can someone tell me how to fix the humidity in my room?I put a clear plastic cup over the sprout for the time being hoping to keep the humidity up in that little area(it has a hole for air tho) I even put a tiny bit of fertilizer in there, but it doesnt seem to be helping...Also im keeping the ground nice and moist.What should I do??

Aannyyone?Please, advice?

its fine......take a chill pill

your lights should be sideways to throw more light

LEAVE IT ALONE!!!! It looks fine! I hope you didn't Fudge yourself by adding nutes this early in the game. I burned my mater kush plant in hydro using 1/4 nutes, & that's on it's 5th node I believe?

lol im growing master kush +1 nirvana lol.
ya bud ur fine. no nutes this early tho, soil is questionable too

they are fine. purple is good. dont put any plastic wrap over them. They don't need a bunch of humidity like a clone at this point. Next keep up with watering. use the weight of the cup to test if it is full of water or dry. pick up when watered to feel the weight. Pick up every 3 to 4 days with those lights to check weight. When light to feel water. if knats are around you have a sign they are overwatered...

Hey scroggy I tried to like your post. Guess we don't have that option now? OP: your lil seedling looks totally normal. NO FERTILIZERS for a while yet. It's a quick way to burn your seedling. Do you know the rh in the grow room? You should. Your temps are good. I'm not worried about the dry conditions at this point in your grow. it's when you dry your buds that you got to worry about ambient rh. Have yourself a beer and relax.

Thanks for the input everyone. Plant seems to be doing great 4 days in, im happy Kinda overreacted,haha.Peace
