hey guys my seedling leaves are curling upwards and the tips of the leaves are pale green.

soil 50% peat moss 50% perlite
I was thinking maybe this could be heat stress? The seedling is under a single 23w cfl


thank you for the help

It's either heat or more likely the pH is out of whack from over watering. Next time you feed add some calmag and pH the solution, I would stay on the high end around 6.3. But keep your ppms in check since it's young, 200ish.

50% perlite - ya the problem is you have a very low moisture mix and arent watering it enough.

Also peat moss - this is unfertilized, do you mean soil or peat moss? Peatmoss and perlite will need fertilizer from the start, soil wont.

You're probably right, my head is stuck in coco mode lately.

Spasmoos,

You rinsed the peat moss thoroughly? Squeezed out all the water you could?

Added a little lime? Peat moss's ph is pretty damn low usually. Ph 4.5ish
