Anyone know what this might be? Rot?

After 4th node i topped. The mistakes were, 1 old soil, too strong fert., bad drainage. So I took it out of the shity pot. I planted it in my garden. I hosed the soil after planting it and then it rained for 2 days.

New growth that looks like pre-flowers are growing out and burning up:wtf:? Its growing strong but what looks like flowers or new growth just gets about an inch then burns up? Iv washed the soil, but after it was planted, mistake.

If you can see iv circeld burned area and a pic of the whole plant. Its growing strong but this small growth near stalk and large branches in other areas of the plant just burn up? Other then that the plant continues to grow larger but close and tight like a celery plant:wtf:?

Any help my friends please:wtf:
