Help with my white widow outdoors

[Weed12]

I started my plant in the little storage box and after 2 days my plant looks green but soft with a red stem.

I became scare to loose one because it was soft then I brought my plant outside the temperature is around 20 to 25 °C plus I feed twice a day with water in spray without nutrient. My soil is from Walmart then I pretty sure isn’t the best but if you know the brand better or compost so we can buy in the shop not online.

I will change my soil when transplanting happen to a bigger container and with better soil.

This is my plant outside after 2 days from the seeding.

it still soft and I need help with nutrient I should give it and any tips for outdoor grow for a white widow?
Someone told me this soil + perite is good

Soil looks overly wet. They don’t need much water at this point. Make sure you give it time to dry out between watering

No nutes right now. The soil you have it in has time released nutes in it. Highly recommend you do your homework and get a marijuana friendly soil for the rest of its life
