My auto flower seedling is growing slow and droopy leaves

[Parker2019]

Hey guys im on day 10 with my auto seedling and things are going bad. I think im overwatering but i cant find any pictures besides severe overwatering to compare. I have a aglex 2000 watt led thats never had a problem with early plant life so i dont think its heat stress, i water every so often when soil seems dry but for the last 3 days its been droopy and growing very slow and yes i know my humidity is very low due to winter but i havent got a humidifier yet

I know sorry i was gonna put more info up but im 90% sure i figured it out i didnt mix my coco right at all someone told me vermiculite is the same as perlite and as a result i didnt have air accessible to my roots because i didnt use nearly enough i probably used a 80/20 ratio and ive also researched that vermiculite isnt as good for aeration and that its more used for holding moisture i guess.....ill try to provide more information next time

My light is a 2000 watt aglex with just the veg switch on
Medium is coco vermiculite mixture
No feeding just distilled bottled water
Temps bounce from mid 70s to mid 80s farenheit
Humidity is low and all over the place the lowest ive seen was 30 highest mid 40s (no humidifier during winter)

Coco is NOT soil, and can't be treated as such. It's a Hydro style grow

Water daily with 1/4 strength nutes
Coco retains no nutritional value in it thus daily watering
