What is wrong with this pepper plant?

[Shawn]

My Big Daddy Pepper plants leaves have brown spots on them.  What is wrong with this plant?  What do I need to give them?  Any help?

The other plant in this garden is doing wonderful.

Of course in person the brown is much darker.

How long since your last R&R? Have you given it any CalMag? Have you looked at the roots?

There can't be too much wrong, if the other plant is flourishing.

I was due for an R&R yesterday.  I was too tired to set it all up.  I guess I will do one this week with fresh water, nutes, mooch and koolbloom.  Believe it or not, I have never really had to do regular R&R's with my water.

I will put it on my list of things to do tomorrow however.

Nutes usually help when my plants develop mottling like that. The question is, which nutes? That's why I just do an R&R if it's near the time anyway.

I've had that happen with my pepper plants, and it's always either too much nutes or not enough nutes - but most of the time for me, it has been due to not enough nutes.

An R&R should fix that, but it's likely a lack of magnesium if you want to try adding a CalMag product instead.

This may have been a phosphorus deficiency. If you see the purpling on the leaves it's my first guess. Some Bloom nutrients should help.
