What's wrong with my plants?

Stoney845 · Mar 18, 2016

So I have 8 plants in my tent but lately three of the biggest which are autoflower have taken a turn for the worse don't know what's wrong I'm not using nutrients being I'm using a hot soil any help would be great

First thought is over watering, curled leaves.

That looks like heat stress to me.Likely from your lights being right next to the tops like it appears in the last pic.

The way the leaves are clawed would suggest a nitrogen toxicity.

Would agree nitrogen toxicity had the same problem when I mixed my soil wrong with a little too much blood meal

What they said ^ N Toxicity
Over watering would cause most of the leafs on the plant to wilt, not curl.
Light burn would cause the leafs to wilt, discolor, wrinkle, crinkle, crumble...

What's the best way to remedy this ? Plain water for a while ?

Pushing it too hard...?

I'd check your temps and humidity are in the zone

and ease off feeding for 10 days

continue with the water avoid over watering

good luck

Thank you appreciate that

Stoney845 · Mar 19, 2016

My temps usually range between 70-80°f and humidity around 40% and I'm growing in a hot soil so haven't fed but guess I will give the soil a good flush once it dries out.
