Leaf color. Day 14.

JarJarGreensstarted grow question 3y ago

The coloration on my first leaves is worrying me. First grow. I really don't want to stunt her. G&B potting soil, filtered soft water, Myco+ in my water, 100w AC infinity Ionboard.

Looks like its getting a bit to cold for her. Temps below 16C/60F will cause stunting and hinder nutrition uptake.

Grey spots on leaves and yellowing The leaves are looking light green to yelloe and there are these dark edges on the leaves are showing up.. Has anyone experienced this before? It was happening a bit before transplant but now it seems to be getting worse. I just transplanted within 24hrs... Stress? Overwatering?

Black marks on leaves of a slow grower.Noticed there's black markings on the edges of the leaves on our slowest growing plant. My initial thought was water droplets sitting on it before it had fully broken out or could it be something else?

These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?
