Leaves Curling Up and discoloration in the Middle of leaves
Papa_Tanswered grow question 4y ago
I read your diary. The leaves discolouration I think is due to a slight magnesium def. I would make an epsom salt foliar spray at 20-50 PPM adjusted to 6.5 PH.
Spray that onto the plant just after lights out so your plant isn’t wet under the lights and gets light burn from droplets. This should clear up your issue.
I see you’re in soil. It also maybe time to start supplementing a bit of cal mag into your feed regimen.
Hope that helps. Cheers 🤙

Overwatering?Can anyone confirm that this curling up is due to overwatering? I don't see any yellow leaves that would indicate overheating. But I read it could also be a nitrogen defeciency?
One pic is upside down, I wasn't stoned taking the pic, honest 👀Week 2

Seedling leaves are discolored and starting to curlNot sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!Leaves. Curl up
