Thanks for feedback. I don't think it is excess phosphorus because I have used heavier phosphorus during flowering stage. I used a 5-5-5 natural fert. But maybe it's cumulative effect. I sprayed leaves with epsom salt yesterday for magnesium. If I don't see turnaround for better I will look into some iron. Whatever the problem has no effect on my brain strain.

The wrong Ph will cause chlorosis as well. Check your Ph.

esox07, I like your comment. It has lots of good information. However, I just wanted to say that the P in NPK is phosphorus (the K is potassium). So, you'd want a fertilizer with the third number being lower; I don't think higher phosphorus would hurt. Cooler temperatures can make potassium more available, too (and warmer ones less available). Phosphorus is said to be the opposite, and good for cold-tolerance, plant maturity, flowering, roots, leaf size and other stuff.

Thanks Shule, I confused the 2. Lot of rain here so I am waiting for plants to dry out then going to water with epsom salt. I sprayed leaves already but rain probably washed it off. Even so, some of the top leaves appear to be turning green on cherry but not the halapeno which is the worse.

Thanks, I get those two mixed up often.
