Day 12: Started noticing little brown marks on the edges of a couple of the leaves.
Don't know what to do or what caused it. Thank you in advance for any help!
Hello friend
You recently transplanted into soil yes? I think you may just be experiencing a small tip burn from nutrients in the soil. Give a week or two and it should be alright. If you can raise your soil ph just slightly so it's above 6.2, calcium is best absorbed above 6.2 so i think that could help prevent some future possible problems as calcium works with many of the other nutrients.
Happy growing. ✌️
Seems to be from the soil being too hot after the transplant, once they get bigger they'll be able to intake more and this won't be an issue. Hopefully, I answered your question and Good Luck with the rest of your grow.
