The Story

So seeds sprouted fast no issues at all.

Theyre about 3 weeks in and have been on water only since FF soil has been said to run a little hot.

3 days ago I added a little bit of organismXL//RO grow//RO foundation to the top soil and watered.

At 3 weeks in they seem a tad small still and as of last night i noticed 3 of the 5 have some blades starting to reverse claw upwards.

Ive been seeing in some places that it could be nitrogen tox or to hot of soil so i gave them a flush last night.

still curling upwards but no signs of getting worse since last night.

Thanks for the help.

Curling up could be from over watering.
