Can anyone tell me what could be wrong with LSD25 ...

I was just about to say what spinner said. Listen to him man. Don't chuck it, just grow it out.

I would agree that it's an issue beyong your control, I'm unsure if it's genetic or viral. If you let if go through flower it won't produce smokeable flowers. They'll be wispy, harsh, and generally unusable.

its genetic try adding different nutriment i have few on each strain that went that way if you five it love and care she will grow big too just longer

Your plant has a virus there is no cure. Check out my FB blackberry grow I had one just like it. It's possibly TMV (tobacco mosaic virus) it can be found in soil,on the seed itself, contaminated garden tools or if you or someone else uses tobacco product it can be transmitted that way also. Personally I pull my plant rather than risk contaminating the rest of my plants because it can be transmitted through contact with the affected plant by your hands and tools. I recommend sterilizing everything that you use to water your plants or tools in 1 part bleach 9 parts water for 5 to 10 minute then rinse clean. I find a 5 gallon bucket with about 1/2 gallon bleach works well. Stuff like this happens when growing plants I have seen about a half dozen grows this month alone with the same issue. Sorry for your loss!🙏

It's a mutation from genetics. One time I grow a rqs critical and it naturally topped it self. It grew a 1 stop growing up then starting branching out. I finished it fine. So don't worry as long as she is growing keep everything in check and keep her happy without stress.

It is a genetic issue , the leaves are distorted. If it's not a genetic issue then it could possibly be caused by a soil beeing too rich in nutrients , but I personally bet on the genetic issue, you have 2 possibilities: 1/ the whole plant will grow like that 2/ the new growth will be normal or close to a normal leaf shape
