There are various causes for yellow spots on leaves.

Have you fertilized? What with?

I have not fertilized. I bought them at a store and was told that it was not good to fertilize. Yesterday I did buy some vitamin B-1 and was going to put it in today. Would that be good enough or what fertilizer do you recommend? I attached a pic see if that helps any. That's how they all look. Some a little less

Whoever told you that is full of moose cookies. Like any other plant, peppers benefit from fertilizing. But fertilizing with the right thing in the right amount.

Vitamin B-1 is a scam Thiamin is supposed to "protect against transplant shock". But it doesn't. The rest of the product is a fertilizer, but from what I've seen the nutrient balance is wrong for peppers, tomatoes, etc. Peppers want a NPK of 3-1-2 (or a multiple). V. B-1 looks like 3-10-3 or 10-10-15. Take the V B-1 back and get something like Miracle Gro All Purpose, which is 24-8-16 or similar. Probably considerably cheaper too.

All that said, I don't see a nutrient problem with your plant. The little wiggly lines near the spots indicate that you have leaf miners - insects the burrow within the leaves leaving little tracks. They are rarely considered to be a pest since the damage is usually only cosmetic, but in your case they seem to have isolated parts of the leaf, causing it to turn yellow or brown. You can feel them inside the leaf, and squish with your thumb and forefinger. No pesticide indicated.

The new growth looks pretty good. Don't sweat it. Let the plant grow. I trust that it's getting good sun?

Here's a link to a paper at a research university that addresses the myth of vitamin-based and high phosphate fertilizers for transplanting.

DmForcier thank you for your help. Should I put miracle grow now or is it to late? Also I should not worry about pods dropping then?

The best, simplest, cheapest all purpose fertilizer is the MG blue water soluble. It sells like for $11.00 per 2lbs can , that can last for ever. AND it has the same proportion as DMF said : 24-8-16 (that is 3-1-2 ratio). I would use it like 1/2 to 1/3 recommended strength but more often. It also contains essential trace elements.

+1 what DMForcier and Seysonn said. I used Miracle Gro All Purpose (water soluble) all season, and it worked wonders. I'd recommend it to anyone. I had excellent results.

@Dennis- "Moose Cookies"?! Haha! What?!

> "Should I put miracle grow now or is it to late? Also I should not worry about pods dropping then?"

Too late? Didn't you read what I wrote? There is NO current problem with nutrients. Fertilize later.

Blossom drop can have any of a dozen causes. Transplant shock is one. Don't worry about it - at least for now.

I like MG shake and feed for tomatoes. That's all I use on tomatoes and peppers anymore.

I use MG "Shake N Feed" too. It is a slow release and has Calcium too. Because it is SR, I use it early on in potting mix (5-1-1), planting hole and as top dressing But from mid season on I use water solubles for instant satisfaction. By then the Shake-N-Feed has lost most of its power

There are few other choices as well. I have never used organic products, mainly because I find them excessively priced for my budget.

Flower drop probable causes:

1. Day temp too high >95F
2. Night temp too low 85F
3. Too much nitrogen fertilizer
4. Too much water
5. Low light levels (reduces fertility).
6. Very low humidity (reduces fertility)
7. Poor air circulation (air circulation contributes to pollination).
8. Lack of pollinating insects.
9. Size of pot

10. Too much mineral in feedwater.
11. Too much grower attention/anxiety.
