first leaves wilting

no nutreints.. the water comes from a filter that i have installed in my house and should be around 6.5 (anyway should test it more times). For the watering, ive been giving 200 to 300 ml every 2 days (no spraying). i havea purple queen that's in her 2 week, she suffered the same wilting shit at the beginning and now she's growing, but those wilted leaves slow down everything (comparing to older grows)

I'm using the bio soil i get at the gardening shop, always thought that could be the problem... my light is a 120W LED, i do 20/4 light schedule on veg mode for now

Lets start with the basics: Arr you pHing your water every time you water the plant? Could you be overwatering? Are you using a nutrient rich substrate or a soil-less nutrient free substrate? What nutrients (if any) are you using at this stage? What light do you have, how hot is it and how many hours a day is it on? Tips - keep your lights on a constant cycle so you dont stress them out. Water small and slowly at the beginning and pH every time. Keep nutrients to half strength if you are just starting with them. Avoid spraying them with lights on - the mist on the leafs can act like a magnifying glass and cause burns if you spray the plants with the lights on. It would be helpful if you can do a diary for the plant so we can see if there is anything dodgy in your setup :)

Maybe the Medium you use is a bit to ,,hot,, for the young Plants. Also dont cut their Lighttime! Thats just irritating them. ( Just keep the 18/6 till flower...) Or i missed the ,,Question,, and you mean those two first leaves that always fall of/wilt/dry out the moment your Plant grows some more leaves...
