If you don’t have a growlog please answer these questions.
What strain are you growing? Is it Auto, Fem or Reg?
Are you growing Indoor or outdoor?
Are you using nutrients? Which ones? How much?
The tips of your leaves are burnt, this can show your soil has too many nutes. It could also be overwatered especially if the pot doesn’t have drainage holes.
Hello and welcome to the community i hope you enjoy your time here and sorry to hear about the struggle. As for tips pretty much what the others were saying its either over watered, to high in nutrients for the babies, or if soil is depleted of nutes or its to dry underneath top layer of soil. Looking at the cup i see not much soil in there and the plant may need more. Since the leafs are touching the edge of the cup i would try to transplant into a bigger pot size and during the transplant determine if soil is moist,wet, or dry and depending on what it looks like will determine how much if any water is needed. Sadly it could be 1 or a combination of issues but hopefully with the help of the community we can get ya right
