First grow in 40 Years

Troubleshooting
1

Just saw some spots on some leaves and was hoping for some help.

Looks like rust to me, I removed the 4 affected leaves.

This plant had a slow start and seems more compact than it should be. It is just over one month old. It has been growing better the last week or so and I clipped at the 5th node a few days ago.
Any critiques or suggestions welcome.

Thanks

I was using fish emulsion last year. This year I’ve switched to dry amendment. I still use the emulsion only now I just use it when I brew a tea.

I was thinking P or K but it really doesn’t look quite like either to me. I am going to make the nutes equal and see what that does.
Thanks

Looks like Calcium sir. Twisty leaves points to look at PH and that makes sense with Ca issues in my peanut. Lemme find ya a chart. Ok and It just dawned on me you said MG… watch for Nitrogen issues up the path a bit. Time to UP-Pot and get some real soil with some Nutes too very soon.

Thanks for your reply. I put it in a 4gal pot and moved to the redspec light. Hopefully it will be happier. The soil that I got at first was pH >8 (which surprised me) it was doing poorly as a seedling so I transplanted it to the MG seedling mix. Just goes to show how important a pH meter is.
Thanks and thanks to the forum
