Hello,
Please someone tell me what to do.
I'm beginner in indoor growing and my plants are a month old. I used NPK fertilizer (one teaspoon in a liter of water) and watered my four plants. three of them have started bending down their leaves as well as bending of the stem close to leaves. I changed the soil after this and saw that roots are black.
There are many answers and guides in the net and I'm confused.
Also, you can see white spots on one of my plants.

those girls look way too young for food TBH. chill on feeding until those cotyledon leaves fall off (the baby leaves at the very bottom of the plant that dont form into "leaves")
if you need told what to do at this point you over your head unfortunately. It seems like you have a dampening problem so your going to have to increase drainage or add aeration to the soil (perlite, vermiculite e.c.t) That indeed looks like a classic case of PM thus my reasoning for dampening off. Only water when the plant droops, and the soil is DRY. I'm trying to save you a headache and it happens to a lot of seedlings, you give too much water too early and they basically drown and suffocate because plants cant breathe water they breathe air like we do.
For food like i said you should wait until your at around the 5th set of leaves when the cotyledons should be yellowing and falling off and thats the perfect time to start food. Most fertilizers are fed per gallon of water where im from (1Tsp/Gallon) so your feed ration is off by a bit my man. your probably burning your girls a top of suffocation. the conversion from liters to gallons is 3.7/1gallon so simply get a gallon of water, use the same amount of feed, mix well and feed from there. toss the excess you don't have to use it all!
that first girl got damp off like a bitch so shes prob lost but the others can be saved. what's the area you are using and how much light? need more info to help
