Bottom leaves are turning yellow and tips turning brown. Older and new bottomer leaves. Temperature is 24-32, I have flushed them a lot. Outdoor.

How old are the plants? Any pictures available?

What have you been feeding the plants, and why were you flushing them?

A bit more information might make it easier for you to get your answers

Probably nutrient burn (too much fertilizer); it might take a few days for the plant to recover.

ammonium nitrate=very strong. also check pH of soil.
