Any idea what might be making this lady so unhappy?

She was fine up until a couple of days ago. The soil ph was high so I added Sulfur. I’ve been pretty light with nitrogen so I don’t think it’s that. I’ve been pretty careful with watering too so I don’t think it’s that either. She’s got 3 little sisters in there with her all in the same conditions and they’re all fine. It’s a mystery! Any ideas?

Too much water. Let it dry out a bit.

All I can say from my tries is too much too fast!

I will suggest concentrated minerals and supps be avoided until you know them. WOW.

Your soil mix looks very rich, not enough aeration. Wood chips aren't the best thing to have in cannabis soil unless you're pretty active.
Lot's of extra carbon. My guess is it might be hard for the roots to grow in, unless that is only a top dressing.

How old is the plant?

Awesome guys! Appreciate this.

She’s about 5 weeks old. Here’s a pic of her with her sisters.

The soil is a bit of a mix of potting mix, mulch, compost and a bit of blood & bone. So it possibly is a bit rich but they’ve been fine up until the last few days. Maybe adding the Sulfur has made the nutes in the soil more accessible? And maybe it’s given her a shock? I’ll ditch the nitrogen for a while, and I’ll ease off the water too (it’s a bit hard to imagine that’s the problem though - they haven’t been getting much water).

Any other thoughts?

the nitrogen bacteria in the soil will concentrate on breaking down the larger wood chip particals and not be so available to the soil and therefor the plant to use for growth.

It’s AWESOME how much knowledge there is here. Thanks again!
