Could this be from the soil being hot?

Thanks, I tried to get close. It's only on a couple tips and I've heard ocean forest will burn your young plants.

with ocean forest,it has enough nutes already init to provide the plant for at the very least a month,i cant see whole plant but that is a burn,so if 200 burn it drop to 125 to 150 with your ro water,the ocean forest dont need the cal mag unless you see signs of needing it mate

I dont see anything serious, but OF is good until at least week 4. Have those tips been touching the soil by chance?
