Wrinkled leaves?

My Super Silver Haze has very wrinkled up looking leaves, and they seem dry. Its growing like crazy and is in veg, about 2 feet tall. Other than the leaves, it seems healthy. Its in a 10 gallon Smart Pot filled with half super soil and half roots organic. Any insight?

Wrinkling is usually a PH issue. You also happen to be growing one of the most sensitive plants out there, so I would make very small changes, then give it a couple days to see if things get a little better or a little worse.

From High or low PH?

I suppose it could be a little off either way. I've grown a couple Arjan Haze varieties and had the same issue, and that was before I had a PH meter. Now that I keep my PH within a safe range, I haven't had the wrinkle problem anymore. Depending on what medium you're growing in, a good range for me is around around 5.8 for hydroponic growing, and around 6.8 for soil. What are you growing in now?
