2 of thirty or so of my plants are turning yellow around the boarders. Any ideas?
What are the cultural conditions?
Light, potting mix, watering and fertilizing frequency.
They are under t8 lights, I bottom water around once a week, I did forget recently (about 9 days) and they wilted pretty bad but bounced back after watering. I use a 24-8-16 fert that I dilute. The potting mix was just a store bought potting mix with vermiculite, perlite, worm castings and some bio tone starter plus mixed in.

Sorry for the " misspellings" posted from my phone stupid auto correct
Should I be concerned about this spreading or do you think it's a nut problem ?
Looks like fert burn to me. Maybe these 2 plants were a little on the dry side when fertilizing? Just a guess.
Thank you Kevin that is definitely a possibility. I have never seen fert burn before and a couple of the plants were really crispy I thought I lost them. I wanted to experiment with topping anyway so I'll make these my experiments. If I rinse the mix really good do you think they will survive? Should I remove the yellow leaves?
Yeah. I think they're fine. Give 'em a good flush and they'll keep on truckin, imo. To prevent future burns, water first, then fertilize shortly after.
I'd leave them...they're still working. it's up to you though-- if the plants have plenty of foliage, then clipping isn't a bad thing.
You can add a little epsom salt with your water or food. This will add magnesium which peppers need to make chlorophyll (the green stuff in plants.) And it won't hurt.
Other than the fact that Epsom Salt increases the overall TDS level in the mix, Terry, which could be the very culprit behind the discoloration at the leaf-margin. Adding single elements is, frankly, unwise, unless there is an indication that the element is lacking.
Josh pardon my ignorance but what is TDS? My plan is to flush very well, which I have done already and lay off the the ferts for a while. As long as it's not contagious I'm not too worried because I probably already have too many plants but id still hate to loose them. I know I have a problem. If they look ok in a week or so these are the ones I'll do my topping experiment on. On the other hand if there is a chance they are contagious Id rather just pitch em to be safe.
Hey, Scott! TDS is Total Dissolved Solids, or fertilizer salts and whatever else might be contributed from your water.
