What type of defiency is this?

[Curtis4661]

I've been having yellowing on my plants that I have found out was a nitrogen problem, and am working on that fix, but this plant has black with its yellowing and looks a little different from the others. Does anyone know what is going on with this plant?

Looks like you need some nitrogen/manganese, idk what's wrong with mine rn it's goin purp whether a deficiency or just genetics

Most cases purple is due to genetics or cold night temps in most cases ....all my outdoor plants get some type of purple some more than others by the end at harvest do to cold weather temps......but I believe if your temps are good and it's not a genetic that will go
Purple phosphorus def can cause that .....don't quote me on that but I think it's something to do with phos

Hi Curtis, it looks hungry .
A good dose of whatever nutrients you are using and it'll be looking good in no time.
What is your feeding regime?
