Hi all,
New grower here. I have a few plants growing in a Kratky-type setup, and noticed some of my plants' leaves are beginning to curl upwards like a taco sort of. They all also seem to be a lighter shade of green than I expected, though they are fairly young.
I have kept pH in check (hovers around 6.0) and PPM is just under 500. Water temp is 68-70° though it can come up to 72 or 73 when I'm not on the ball. The plant is growing closer to the LED light above, so maybe it's heat stress? The light does not emit a lot of heat though. Any ideas what might cause this curling?
