Hi, it is my first time growing autoflowering stra...

By looking at your diary and seen the stats I can see a few things that will lead to damages here . Firstly because your medium is soil you should raise your PH to optimum levels (6.5-6.8) , the second thing I see if you are using A LOT of nutrients for a very young seedling . I would reduce the amount of nutrients you are using to just your basic needs until your plant is showing signs of a deficiency . If you keep feeding them nutrients in that amount when they are young you will eventually cause burns . The plant cannot uptake all the nutrients you put in the soil , so its best if you do it every second or third watering . Right now at this stage of growth I would only be giving them a rooting agent , chelation agent ( humic / fulvic acids ) and a little bit of CalMg then in a couple of weeks you can start adding more nutrients . You will see auto flowers like nutrients when they are a little bit older but as for this moment less is more until she develops a little more . I hope this info serves you well on your journey ! -Happy Growing!

You are using soil, so let the plant feed on the soil and start feeding when you see the first signs of defiiencies on the lower leaves. Then when you start feeding, it is better to give small frequent feedings, rather that one strong one. I do that and start feeding around week 8 (when using 11 liter pots); start with a strength of 0,7 to 0,8 EC (350 to 400 PPM), give the plant a week and watch how it reacts: does the deficiency continues? Then up the strength 20% to 30% more, does it turn dark green showing signs of excess nutes? feed less. It's difficult to give a schedule and I advice against following one, because it depends on how much soil you use, how much nutrient it has, how much light you have, your temperatures, your humidity, etc. with a nute strength of 0.7 to 0.8 EC it's difficult to do much damage, and if it turns out it was too little, you can always feed in 4 to 5 days a stronger solution. Hope that helps
