Hi,

I've been growing this Jack Herer from seed and they're just coming up to 2 weeks in veg.
Its a hydro setup and they are under a 400W metal halide which is 11 inch from the tallest plant.
They have only just made it to full strength nutes after spending the first week getting 1/4 then 1/2 strength before hitting full strength a few days ago.

The problem though, is that most of the plants are showing this leaf curl in varying degrees.
It starrted on the lower leaves but now new growth is doing it and I'm getting worried.
I can't see a corresponding symptom in th faqs so I hope someone here can diagnose.

Many thanks.
