Hey y’all,

I cannot for the life of me determine what this marking is. It’s dark looks bronze almost brownish black. It’s not in spot form but it streaks along the interveins and starts at the edges of the plant. Currently it’s only 1 leaf that has it bad but it’s starting to spread from what I can see.

EDIT - It is strictly at the top of the plant from what I can see.

This third pic you can barely see it but it starts at the edge

I wouldn’t trip too much on one leaf. Your plant looks great. If it were to spread and looked like that everywhere it’d be one of the micronutrients or bloom nutrients. The plant looks like it has plenty of N and it might be time to feed more p&k bloom stuff which would have the micros you need for bloom.

That’s the thing I’ve got back on my base nutrient which is mega crop which is 10% N recommended dosage is 6g per gal. I feed at 2.5g and use bloom enhancer and pk boosters that are richer in P and K.

Before you add or remove anything ensure your PH is correct for the medium your growing in. That said, judging by the color of your leaf stems and how the deep red color is moving into the veins of your leaves and guessing you have red or purple streaks on your main stalk or branches you have a phosphate deficiency. If your PH is way out that would be the cause if your PH is Good add P and wait a week or two and it should clear up.
Other than light water and nute's the correct PH is critical to a healthy plant otherwise no matter what you throw at it will be all for not.
I'm guessing your PH is out which in turn is causing anthocyanin in your leaf stems and possible branches this is a indicator your plant is stressed and lacking a nutrient. Too much anthocyanin and the stems start to shrink and block critical nutrients for healthy leaves and branches thus leading to your rust colored spots.
Clear up the deep red on your plant before flower as it will lead to serious problems during bud and phase have a big effect on your yield.
Cheers!

Unfortunately it’s already week 5 flower. Throughout the entirety of its life the stems have had a purple hue to them but I will take your advice and add more P and K. For now the PH is 6.2 in coco. Which is a little high but not out of range.

Can I see a full shot of the entire plant? That would assist me on advising you, thanks!

If your already 5 weeks in flowering you should be fine trying a little more P, your plants look healthy over all. Don't sweat those few rust spots at this point.
