disease Checking In on Some Leaf Blemishes

[NJChilehead]

We've had a heck of a cool and rainy spell here in the Northeast, and as expected, I'm finding some light fungal issues on my plant. I found two lesions that I'm a little more concerned about and would like to run these by the experts here to make sure I'm not seeing anything communicable or pathogenic (esp. viral/bacterial).

The first two photos are on the top and underside of a leaf of a C. pubescens that I'm growing out. Since the lesion appears on both sides, I'd like to rule out anything serious like BLS.

These photos are of sunscalded leaves (I didn't harden them off well enough). Coincidentally these are on the same plant. Does this look like anything beyond sunscald to anyone?

This last leaf was removed from a C. pubescens that is currently being grown indoors. I did find 3 aphids on the plant, so I'm hoping that this is an aphid feeding lesion, but again since we're seeing a lesion on the top and bottom, I'm hoping it isn't BLS or something else that is serious.

Thank you for your help!

For what it's worth, it all looks like very normal stuff to me and not any disease or even aphid/insect activity.

Funny to see the spider in the second photo next to your hand. Sometimes when I'm taking pictures I won't even notice something like that's there until afterwards when I see it in the picture.

Totally agree with CD all the babies have funny spots & stuff at plant out time.
To be on the safe side I spray my plants with Southern Ag Garden Friendly Fungicide, 1 tsp per gallon goes a long way.

I concur with the others, these sorts of blemishes are a common sight and completely normal. Saw them frequently when I grew my peppers last time. If it gets bad on one or two individual leaves, the plant will just drop the leaves, the same way we shed hairs or dead skin.

many of my pubes (especially giant yellow rocoto) have that yellow/brown discolouration on them too, and they did last year for me too.

i chalk it up to either too much or too close light, or that it's a nutrient deficiency from maxing out their tiny pots and being root-bound. it especially happens on the largest leaves, so i feel like maybe the plant is consciously choosing not to "support" that large leaf and instead steals the chlorophyll back and will drop the leaf in favour of trying to grow new growth.

the other spots you've shown, i am not familiar enough with pests/viral/fungal/etc to give any suggestion.

Thanks everyone, I feel a little better about this. I'm still keeping an eye out for any changes, too. We've had quite a bit of wet and cool weather so I'm hoping that the plants stay healthy!

We are having a wet cooler than normal spring. Too many fungal problems when that happens.
I have been using 1 Tablespoon per gallon rather than the normal 1 Tsp of the Garden Friendly Fungicide on everything.

Thanks Marturo, I'll keep this in mind, hoping that I won't need it!

That is a nutrient deficiency IMO. Given the size of the plant, you're starting to get lock out. What is your soil ph?

Good call on the nutrient deficiency! The plant has recovered beautifully. I suspect that part of the issue was that the roots were underdeveloped and not adequately taking up nutrients, and also that the weather was very crappy (cold and rainy) which may have exacerbated things. Right now she looks great!

Glad to hear it bounced back. Cold temperatures and or high stress can slow nutrient uptake for sure.

I always sprinkle beneficials around the roots when transplanting and then water with EWC water. It helps plants and roots recover very quickly.

I use water that is filtered to get the bad stuff out, than ran through another filter to put the good minerals back into the water. At least when it doesn't rain enough. If you ever try that always make sure your water ph is appropriate. You need to know the soil ph to know what your water ph should be.
