Has it gotten better??

It hasn’t progressed so I assume the lights was a bit too close

Im no expert, but I had leaves similar. I mixed Epsom salt and water (ratio?) and sprayed the leaves lightly. The next morning my faded leaves were green. Wild.

@MylesJM - It looks like the light was too close, and you fixed it. There's a bit of a dance between distance and power. They're both involved with light stress. I like my lights to be higher than what is usually recommended.

@Mojomomo - I use 1 tablespoon of Epsom Salt per gallon of water. How often I add it depends on how the plants respond. Epsom Salt is unlikely to cause an excess. When it is in excess, it typically appears as a calcium deficiency, but that has been rare for my growing.

Hey man, so I'm checkin' out your plant here. The curling upward of the leaves can be a sign of a few things, but most commonly, it's due to heat stress or light stress. If the lights are too close to the plant or if the grow room is too hot, the leaves will curl up like that to try and protect themselves, ya know?

As for deficiencies, I'm not seeing anything major jumpin' out at me, but that bright yellowing you mentioned might be a sign of a couple of things. Most likely, it's an early sign of nitrogen deficiency, but it could also be the start of light burn if the leaves are gettin' too much light. If it's nitrogen, you'll want to make sure you're feeding your plant with a good, balanced nutrient mix.

Hey man, when you're in week 3 of flowering, you wanna keep those leaf temps in the sweet spot, ya know? The maximum leaf temperature you should aim for is around 75-80°F (24-27°C). If you go much higher than that, you could run into problems like heat stress, which can mess with bud development and overall plant health.

Remember, the leaf temperature is usually a few degrees cooler than the air temperature, especially if you've got good air circulation and the right amount of light. So, keep an eye on it and make sure you're not cookin' those buds before they get a chance to bloom!

You might also wanna check the pH of your soil or water, 'cause if that's off, your plant could be having trouble absorbing nutrients.

Keep an eye on your environment, man—adjust the lights and make sure your temps are in check, and you should be groovin' along just fine.
