Heat or light stress??
YWLganjisanswered grow question 4 years ago
I had the exact same problem where your leaves start curling inwards and I found out from my research that it was either 2 factors heat or light the heat, during summertime it can be hard for you to keep the temperature down so I would recommend buying a aircon unit,
temperatures between 20–30°C (70–85°F) during the day. Growers tend to agree that the ideal temperature is around 25°C

Yes. Either or both. Solution is the same, move your light up a bit.

Twisted leafs inner partLeafs are twisting but mainly inner part. See the photo. And it does not progress. It stayed at the bottom of the leaf
I assume three factors:
Wind
Excessive humid
Cold nights
They got Nutes at all, only from soil (pragron lightmix)
I would say shity PH, but i check it every time

Leaves rippled ? What causes this?These are pics of day 13 seedlings. The larger leaves show signs of something but I don't know what. They are Blue Dream Autos in a 50/50 mix of Happy Frog and Ocean Forest. Temps have been 74 degrees F with 50% humidity the whole time. May be nothing but this is my first.
