WTF Is This?

I've got several Bolivian Rainbow peppers under my 400w Hortilux "blue" MH

They are growing well and flowering, but there's white bumps on the bottom of the leaves. :?

It looks almost like a fungus and is only on the peppers.

I had the same thing happen to my other hot peppers I tried last year, and I've noticed it on the peppers at the local Hydro store as well.


Can anyone answer what the hell this is?

.4 ) Is there a consistent fresh air supply? Yes
.5 ) Do you have an exhaust fan and a circulation fan? Yes both
.6 ) What are the bulb wattages, kelvin ratings, and schedule? 400w Hortilux "Blue"

Your medium:
.7 ) Specific brand and type of soil, (coco, peat based soilless...) and anything you've added to it. (vermiculite, perlite, worm castings...) FFOF no additives
.8 ) Size of container. .5 L

Your nutrients and water:
10 ) Source of water? (tap, bottled or filtered) What's it's ph before adjusting? Tap
11 ) Method of checking water ph. (ph pen, test strips, aquarium test kit...) Pen
12 ) Method of adjusting water ph. (phosphoric acid, white vinegar, hydrated lime, PH Up...) Not adjusting,
13 ) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule. Not feeding the peppers.
14 ) How often are you watering between feedings, and how much per watering? as needed
15 ) Any additives or tea's? (Superthrive, CalMag, molasses, Mother's Earth...) No
16 ) Are your ph levels stable, or do they fluctuate? Stable
17 ) What is your ingoing water's ph? ...your runoff ph? Inbound around 8 not watching runoff.
18 ) Do you foliar feed? If so, with what, how often, and at what time do you spray? No

Your growroom:
19 ) Indoors or outdoors? indoor
20 ) What size of closet, room or hut?4x4

are they hard or soft? Do they come away if you rub the leaf gentley or roughly. need more info. Check the bottom of the leaves with a magnifying glass to get a better look if you think it may be bugs.

DISEASES AND PESTS

Chile peppers are generally quite healthy. Pests are an occasional problem. Tiny green aphids sometimes cluster on the tips of branches. In large numbers, they suck plant juices, which deform the leaves and steal energy from the plant. Aphids can also spread deadly viruses. A strong spray of water from the garden hose can knock aphids off the plants. Caterpillars, including corn earworms and corn borers, destroy the fruits; hornworms eat both fruits and leaves. For information on controlling any pest infestation, contact your local Cooperative Extension Service or ask for advice at a local nursery. Chile peppers are prone to a few virus diseases. There are quite a few viruses in peppers; the most common is tobacco mosaic virus, which causes mottled yellow leaves and misshapen fruits. There are no cures for viruses so the plants must be destroyed. Prevent the disease from spreading by controlling aphids.
 
Thanks for the replies. It's NOT bugs, it looks almost like a fungus kind of growth, and does not rub off when touched. Something about this site resizes the pics, because they are HUGE files and in the full image you can clearly see what's up.

I've sprayed with Serenade, but it doesn't seem to be helping. The leaves are not yellowing on the top.


The other hot peppers I had did the same thing, but it cleared up when I moved em to the front window.... so I'm somewhat wondering if it's something to do with the raised humidity in the grow room. (ambient in my house is about 15%)


I'll try and get a tighter macro shot so this site will show some resolution.

hey man i dont know what it is. but i would recommend not buying a plant froma hydro store it is kinda asking for a pest or disease. i would start your own or go buy all organic plant cuz they dont get pest and and disease as easy.

It kind of looks like blight, but hard to tell. More humidity could certainly help the growing requirements for various fungi. Good luck and hope they bounce back.

Thanks, I was thinking that at first too, but the Serenade should have had some effect in knocking a blight down, and NOTHING :(
 
None the less, I think I've found it. Down towards the bottom of this thread on Gardenweb is a much better pic that looks EXACTLY like what I've got goin on, and a NAME!!!!! Edema. http://forums.gardenweb.com/forums/load/pepper/msg0317181726509.html


While this doesn't specifically talk about peppers it does make sense with my problem.

I've got 5 plants total all the same strain of pepper, all in need of up potting. Since I'm not gonna adjust the environment (suited to my medicinal growing) I'm going to see if different soil conditions will help clear it up (more pearlite, and or aeration containers)

Also, On my Habanero I found out it likes an alkaline soil PH 9 or so, and it perked right up when I stopped PH down usage. So I might play with the PH on this strain a bit..... Need to do more reading and see if I can find the proper inbound PH before I drag my plants thru the coals.

U can send pix/samples to ur county extention service, they're usually linked with some college.
Look up online county extension service for the county u live in. An email exchange might solve the problem or you may have to send them samples. I've never seen anything quite like it other than those white bumps the plants look fine. GL
