Hm interesting, didn't know that! I'll be sure to watch phosphorus more closely. They get full sun from 8:30/9 am to sunset (around 8:30pm). What about nitrogen? I haven't been giving practically any N because one of my tomato plants started to claw and read online most fruiting plants are very sensitive to it. But the leaves on my jalapeno are a little yellowish. I will say though that they're looking better than when I started this thread... I looked today and found some little jalapenos and red peppers growing (although you guys told me to pinch them off... I can't bare to do it now lol).
