What is this?

[Tyleb173rd]

This lady is in recycled soil. Overwatering?

I’ve added cal/mag to my water

New growth affected/top of plant?

I had exactly the same looking problem with my plants. Necrotic lines in the margins.

It was due to excess manganese (or some other trace element) that was exaggerated due to low RH.

It fixed itself up when I stopped feeding them the root stimulant containing manganese and got my humidity back up.

Thanks fella!! I’ll crank up the humidity right away.

If that doesn't solve the problem after about a week. You may find, like mine- that your super soil was too hot. I had to dump about 12L of rain water through mine to clear out the excess. Called leaching.

If i told you i use Mammoth P in recycled soil at full strength while in veg would you think, or does it look like, it’s phosphorus exces?.
