Leaves turning away from the sun?

[wiesser]

Sorry I don't have a pic, will try to post one soon, but some of my plants are turning away from the sun in the afternoon. The leaves are rotating away from the sun, some of the fan blades are actually starting to twist to shield themselves. I thought this could be a sign of under-watering, but my pots get soaked real good. Im in 200 gal. smart pots, outdoor. Plants are very large, way bigger than the pots. Using all organic soil. Just wondering if this could be a sign of some deficiency? Hoping some of the great outdoor growers around here can help a brother out.

what are your temps? That is a stress reponse, though not to under watering imo

Temps have been great, 75 - 85 everyday, 55 - 60 at night. I thought it could actually be over-watering, or a combination of under-water/over-watering, water stress basically. This is my first big outdoor season and it has been a roller-coaster with the watering.

Those poor ladies need some shade during those miserable hot afternoons. When leaves try to shade themselves from light like you are describing its to reduce the light that is hitting the leaves.

Its possible that if they are under-watered and that it'll make the situation worse. Only you can figure that one out, but id suggest getting yourself an Irrometer Tensiometer to help you gauge moisture levels in your media. They're a great investment for your garden, along side a hannah suction lysimeter.

Maybe you can find a way to shield them during the worst hours this occurs. You dont have much to lose since the leaves really aren't gonna be very productive if they're trying to reduce the amount of light hitting them. Good luck, and treat those ladies right.

Do you water enough to get some good runoff from the bottom of the pot? Have you checked the bottoms of the leaves for any bugs? Post a pic or two of the situation.

Problem was over-watering, things are back on track now after letting the pots dry out for a bit.
