Need help with this plant

[Tjgrows]

Hi I’m just wondering if anyone can point me in the right direction with this. Been trying to correct it for awhile being too lean towards a potassium deficiency from a nitrogen toxicity. Anyone else have any ideas? First picture is from 2 days ago. Second is from this morning.

You have got a calcium deficiency.
The scared leaves will crisp and die If you fix the cali deficiency the new growth should start to look better.
It will get worse before it gets better sadly

The brown spots are a classic sign btw for future reference

That looks bad tho. Luckily someone is helping you! Good luck!

Had the same problem problem start watering with cal mag everytime it will slow down and stop but all the ones that already got it will crisp and dry up amd die most likely
