I started some peppers from seed quite some time ago. They have been growing great in a south faced window their entire existence. The weather up here in Minnesota has been pretty decent the past few days so I figured I would do some hardening off. Here is how the hardening off process went:
Day 1 was 2 hours in the shade then back inside
Day 2 was 4 hours in the shade then back inside
Day 3 was 2 hours in the sun then back inside
Day 4 was 4 hours in the sun then back inside
Day 5 started the problems. It consisted of a full day in the sun.
Day 6 was also a full day in the sun
When I went to bring them back inside after day 5, I noticed multilple discolored leaves on my Jalapenos, Carribean reds, and Barrackpore 7 Pot. They were of a whitish-grey-tan type discoloration. It wasn't that bad at first so I decided to try another day of full sun on day 6. When I went to bring them in then, the leaves were even more discolored and 4 leaves from one of my carribean reds up and fell off on their own. The plants that were being hardened off were 3 Jalapenos, 2 Carribean reds, 1 Barrackpore 7 Pot, and 5 Blushing Beautys (the blushing beautys do not have the problem that the others have and all plants were lined up in a row right next to each other.) Pictures below.
This is the Barrackpore 7 Pot. The outer bigger leaves are the affected ones.
This is the same Barrackpore 7 Pot as above next to another seedling that was not hardened off. This Barrackpore 7 Pot was just as green as the seedling next to it prior to the hardening off process.
This is one of my Jalapeno plants. My hand is holding a normal leaf and right next to this one and directly below it as well are 2 examples on this plant that are affected.
This is a zoomed out picture of one of my Carribean Reds with a big bare spot in the middle, the one that shed some leaves.
This is a close up of some of the affected leaves on this Carribean Red.
This is a picture of one of the leaves that spontaneously shed from the Carribean Red.
The only variable that has changed the past week was the plants being outside for a period of time. Oddly, the Blushing beauties (not pictured) that had the exact same experience as the ones above were not affected at all. A friend and fellow hot pepper member who I spoke with and explained what was going on but has not seen them yet thought it might be 'sunburn' which is something I was not aware plants could get, and if that was the problem, then why were the blushing beautys not affected? They are all now back inside in their south facing window until further notice. Can anyone please shed some light on what may be causing this?
