So this is my first year growing, and I was just curious if flower color and pepper color variation is normal? I have two purple ufo plants growing (I planted 6 but gave the rest away.) One in Hydroponics and one was in Coco inside and was recently planted outside. My brother has one as well that I gave him that was in the same coco set up until he planted it out around a week or two ago. The one that I have outside has almost completely purple flowers, and the peppers quickly change to purple as they grow larger with just a hint of green remaining at the top as they grow. The plant that I have in Hydro as well as the one my brother is growing have white flowers with a purple rim, and my peppers are still green on the hydro plant with no hint of purple. All three plants were from the same batch of seeds (I ordered) and have been fed the same nutrients until about 2 weeks ago when the one went outside. It had begun flowering the solid purple flowers while still inside on the same nutrients.
I'm not really concerned about anything, just more curious what could cause this and maybe some of the science behind why they may be different.
