Do you see how the upper leaves are more yellow than the lower shaded leaves? If the cause was deficiency, that color scheme would be flipped.

Do you see how it looks lighter at the top then at the bottom? Well in person it's all the same green color so it must just be the camera being closer to the intensity.

Nope. I can see darker green around the edges as well. Some of them very close to the yellow ones. It's not consistent enough to be the camera. No one is jealous and trying to sabotage your plants. Honest, helpful advice is to raise or dim your lights.

A huge difference. Especially when you’re comparing to low watt hids like that. It’s a bit different when comparing the bigger leds 600w+ to 1000w DE but yeah that 400w hps is outclassed easily by any modern led in the 2-300w range

I'm taking that "evidence" with the same grain of salt as I I would take a twisted body / duck face selfie as a chick's proof of not being overweight on a dating app.

But let's just agree that they aren't fading. They are still clearly heat stressed. But whatever, they're your plants. Do what you want. I would like to stay updated on them just out of curiosity though.

What kind of stress do you think that is that you're seeing? You say heat stress but there's literally no radiant heat coming off of the lights anywhere near the plant tops the heat only radiates about 4" off of the bottom of the lights and the plants are clearly farther away from that and the grow tent ranges from 73ﾟ to 79ﾟ with adequate air flow.

I'm gonna go out on a limb and say my observations of why this forum has such a small community is because you've become a small community of know it alls who circle jerk each other and alienate any new people. There are plenty of others places to socialize and interact..
