Help me diagnose these yellowing leaves please

Hey! These pics are from a really nice commercial operation and I’d like your opinion on the yellowing leaves. I want to say it’s probably due to flushing based on what I know about the grow, but of course it could be any number of things including nutrient burn. What do you all think?

Plants in flushing will fade out and some will show deficiencies because of flushing. Other than that I can see some blades tacoing probably because of heat stress. Too close to light or hot grow room maybe? Tips of the leaves are burnt (overfeeding)but some people push their plants like that so it not unusual if you know the strain in and out and what it can handle.

Nutrient burn, must have been from the last feeding before the flush started

I’m thinking rooms too hot, light burn or bleaching with a touch nute burn.

Tough to tell from pics but top calyx’s look bleached ??

Don’t think much to worry about as they look almost done.

Hope this helps

I see Nitrogen burn and heat stress/light burn i’m assuming from the HID lights.

Light(s) is too close, like @sponge said the leaves tell all :wink:

That’s what I said from the start. Back those lights off. And cut those nuet by at least 25%

Looks like heat and humidity. Also looks like a bit of underwatering.

That tacoing is a dead giveaway for heat and water. The ridges in the leaves are super defined no swell at all. shows they are dehydrated.
