To fix it, go to quarter strength and the extra run off should start rinsing the excess nitrogen out of potter.

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?

Unhappy seedlingSee the photo of one of my seedlings that appears quite unhappy. My guess is light/heat stress, BUT I have 8 other seedlings growing right next to it, under the same grow light, in the same soil, that are doing just fine. See 2nd photo of another of the same strain that's fine.Week 1

Hey guys. Leaves not curling upwards as such but I'm getting some leaf tips that seem to be reaching upwards slightly. Does this mean I need to up her cal and mag intake? I read somewhere if the leaf tips are starting to "pray" towards the light it could be a cal/mag def?Week 8

Twisted, yellow/brown tips.Hi,
My plant has shown signs of a nutrient excess throughout its complete cycle. It keeps to the tips of younger the leaves that have a tiny twist in the end. I don't think it's the light as it also affects leaves in the lower canopy. I keep on flushing but nothing changes.Leaves. Tips - Burnt
