Can you show a photo of the whole plant. If that came from the bottom of the plant, it's probably normal shedding of old fan leaves that stored nutrients. Salt buildup (which can result in nutrient lockout, acidic soil) is common at this stage of growth. But, if the rest of the leaves look good, it's probably just shedding unnecessary lower leaves now.
Did you change your nutrients when you went into flower. Sometimes people cut N too early. (I'm not sure it should be cut at all. But, if I do it, I do it in mid to late flower. Often people think the moment they change the lights to 12/12, they should switch to a "bloom" formula. That could cause the plant to draw N from old leaves.).
I'd like to see photos of the entire plant.
Are you kidding dude? I asked for help and your trying to bash ledsThat's a tiny leaf! Are all the leaves that small? You must be using LED?
I have trimmed most of the leaves that have had damage off, they are all off the bottom and it effects a couple fan leaves but no newer growth or the middle growth. I haven’t defoliated like I usually do so maybe that’s why I’m not use to shedding here’s a pic that I have when I get home lll do a new one with normal light. I can’t really find any of the yellowing leaves right nowCan you show a photo of the whole plant.

I already said I will take one without the light! It was just the only one I had at the time thanks homie here is one of the last effected leavesGive the picture of the plant/plants ( whole view ) without purple led on ( so if any pest/ deficiency are more obvious)
just too hard to analyze with that purple going on , if you can do that, I’m game
24 :) the light wouldn’t be able to at 10. There topped 2-3 times 40 something day veg time and its 17 days in flower I’m happy with themThose are some tiny plants, that LED is 10 inches from the tops isn't it?
Posted one without the light, it’s only been the lower leaves of the plant new growth has been great. I appreciate all the helpThey look great. It's probably just normal die off. (If you reduced N, it could be related to that. But, sometimes it just happens. The lower leaves aren't getting as much light as before. The plant's focusing all its energy on the buds. It cannibalizes itself a little.). If the rest higher leaves aren't showing deficiencies, I wouldn't worry about it.
It might be fun to try this next time. Buy some white posterboard at Walmart or an office supply store. Cut out discs to cover the container. Cut a slot from edge to the center (for the stalk.). I did this once for gnats. (I made two disks per plant, so I could cover the slot, making access harder. It helped, but they still found their way into the soil around the stalk.). Anyway, what I noticed was that the reflected light seemed to keep the bottom leaves healthier, viable. You might do that to 1-2 plants next time and see if it makes a difference compared to the other plants. It would be interesting if the others dropped leaves while these didn't. I assume that would be better for the plant to keep those stored nutrients longer.
It also kept the moisture at the top of the soil more consistent with the soil an inch down. I never noticed any mold. But, I'm in a dry environment. If you're in a humid location, that might be a concern.
Just an idea.
I’m in a extremely dry location, I’ll keep the poster board in mind. I don’t think it’s the light tho. I hope it’s just natural defoliation I appreciate all the helpIt might be fun to try this next time. Buy some white posterboard at Walmart or an office supply store.

Yup, normal. The plant is using up it's stored food. Plant looks great.They are in the early stages of flowering and the plants lower folige has starting turning yellow with the stems staying green. I’ve added some extra nuets to see if that would help and it didn’t. How can I deal with this so I don’t lose this crop

I have been being very light with the feedings, that’s why I I thought I was getting under fed and added a extra batch. I usually defoliate so I never have this problem I guess you never really know what’s going on until things go wrong! Thank y’allIt isn't unusual at all for the bottom fan leaves to yellow and die off during flowering. They usually don't yellow and die off until a month into flowering, but a slight deficiency of Nitrogen can be a reason. You probably shouldn't add too much fertilizer during flowering, depending on how far into it that you are. If the light can't reach the bottom leaves, they will yellow and die off as well. I would try to check your TDS and Ph to make sure that you aren't seeing a possible developing lockout. I recently have followed some growers that are seeing big spikes in their nutrient levels during the start of flowering, which are causing nutrient lockout issues. A value of 2500ppm was quoted as the "too much" cutoff by a member who has more experience with high nutrient issues than I have.
I think you will be fine, just exercise moderation in feeding and general upkeep.
He’s stuck in 2015Lol. I'm using LED. My plants/leaves are just as big as when I used HPS.
