I have 4 seedlings all that have started curling their leaves. They are only at 1/4 of the recommended dose of GH nutrients. Ph had been around 6-6.5 the part few days. Anyone got an answer?
Leaves curl all the time.
For many different reasons. You won't be able to identify the cause on such a young plant.
Like I said, it's too early to start worrying about it.
