Sick looking

A better grower?

What you see there is potassium deficiency. The yellowing pattern and browning spots but not “burnt” looking tips are classic characteristics of it. Your first hint is how it’s hitting the new growth much more than the lower growth. Indicates an immobile nutrient deficiency. Potassium is your culprit here. You need to get more of it in your feed to your plant. Happy growing!

When in doubt ask Nobody01👍👍 From The White House.

If dr green thumb is right which very well could be... as iron and sulfur deficiency are quite similar. Same thing applies most likely ph.

I have seen caused by huge change in lighting aswell... but that would fall under environmental stress I suppose... Stress related.

Aren't you on the top of the grow questions? I think you know the answer to this one.

Looks like iron deficiency fam... either ph or something else stress related... what are ur levels like?

You need to go down to the earth's core and score you some of the most abundant element on earth.... Fe aka iron. Or maybe just play her The Number of the Beast....that might be enough Iron for this maiden.😁
