I have 1 word for you GENETICS
I had a cut of blackberry that even if you grew perfect it sucked ass.
I now have a GSC cut that you can just throw in the room and half-ass it and it will always come out fire.
Your seedlings are damping off (Look it up on google)
I have used rapid rooters and also I have popped seeds in coco or rockwool. Several ways to do it,
You can take off some fan leafs after stretch to increase light penetration.
I just cropped the cookies and it came out fire.
Im rocking the forum cut.
