health Brown/greying of leaf edges with affected leaf areas feeling thin and empty.

[pain is desire]

I've noticed some leaves are turning brown/grey and they feel quite thin on the affected areas, as if the leaf cells have died. Some of the affected leaves feel quite dry and papery whereas others feel soft and squishy. Some of the plants are dropping the affected leaves. I'm growing indoors and have been fairly consistent with watering as well as ensuring they fully dry out. I've been feeding using the bio buzz range. At the moment it is at minimum dilution using bio-grow, bio-heaven and acti-vera. The affected plants seem otherwise healthy and are all putting out new leaves. I'm worried that it is some form of blight or bacteria and that it is going to spread to my other pepper plants. I've attempted to quarantine the affected plants as best as possible but I'm in a flat and it's still a bit too cold to get them outside.

What is your humidity & what do you use to keep the air around the plants moist?

Temp is 74F with 58% humidity. See the fan & the cool mist emitter? Early pics.

Last week & the temp & humidity are the same & all the girls still love it.

I am envious of your setup! I don't have a hygrometer so can't give any accurate humidity readings. My flat is really damp so had assumed I wouldn't need to do much for the humidity except the occasional misting of leaves. When I do occasionally run my dehumidifier it usually reads around 60-65% humidity but I'm not sure how accurate this actually is. Do you think this is caused by being too dry? It has only shown up in the past week or two which would make sense in terms of dryness as the weather has improved so I've had my windows open.

Believe me I am still envious of my New setup. 3 seasons ago we had two double 8 foot HO Fluorescent light fixtures.
Long twisted heating cables that burned our flats, I have no pictures of this less than perfect way to start seedlings.

Do you think this is caused by being too dry?

From what I can see of the rest of the plant, all is looking good with the stem & other leaves.
To me I see no circles or areas that look diseased areas on the leaf. My gut tells me low humidity may be the cause.

What Are The Low Humidity Symptoms In Plants?

Low humidity can have a significant impact on plant health, particularly for those species that thrive in high-moisture environments. Identifying the symptoms of low humidity early on can help you take corrective measures and ensure your plants remain healthy and vibrant. Here are some common...

The girls like it warm & moist, not cool & moist, in their protected world.

Something like this would be helpful, I have one in the chicken coop & one in the Plant room.

I have a couple of those.

Not an authority on this matter by any means, but I have noticed my humidity is usually 20%-40%, and I do not have anything like the OP is experiencing.

The temperature is usually between 70°F (lights off) and 90°F (lights fully on).
