Leaf Curling

Jensocide
Jensocidestarted grow question 2 years ago
One of the plants is getting leaves turned up. Currently they are off to the side in my main tent just picking up light from my plants in flower. PH was 6.5, ppm of 800. Water temp is 71F. Is it light or something else?

Could be environmental... could be a little too much of various nutes that can cause similar symtpom. 800ppm isn't especialy high, but is a bit high and autoflowers are notoriously picky eaters. i don't see other symptoms, so double check pH of runoff and see if it is drifting. Too much heat or light can make a leaf "taco" too. eliminate possibilities of environment and pH before fiddling with nutes. i have a table of nute ppms each week in my diart. i have hard water so i have to use somethign clsoer to ~650ppm, but the npk values are good. N/P/K ppm of 120s/50s/190-200ish, respectively... within 5-10% is probably good enough.

The only thing I see not listed would be your light height, I would raise them then watch any new growth. If everything is dialed in it could be genetics. I wish I could remember who I watched, but they said in there strain that the leaves will curl like that but it never does any harm

I Would say its light stress personally. As no yellowing of the leaves so isn't nute burn or overwatered
