Hello, I was hoping someone would know the answer to this for me. On the very bottom leaves on my plant the veins on the leaves are turning yellow while the space in-between stay green. This is the only plant that has it. Im feeding it fox farms trio fertilizer ( but had to cut back do to toxicity) and have it under a mars hydro ts600 led light. Thanks J

I'd wait a little bit to chop personally. Cannabis plants do tend to yellow at the bottom when they get close to maturity. If you had to cut back due to toxicity she might be getting deficient depending on how long since you did that.

It's completely normal for the leaves to start yellowing starting at the bottom once they reach their end. This means the plant is sucking all the nutes from the leaves in order to get every last bit before she's done.
What week of the flowering stage are you i and what percentage of white hairs have turned dark?
Are you still feeding the plant or are you flushing already?

Based on the one photo of the flower you have 4-6 weeks left before it's ready to harvest. It'd be a huge mistake to cut it down now.

Something I learned this grow about plants in general. All the nutrients are needed in the right levels for any of them to be taken up.
I was using too much cal/mag. I just needed the mag part of it. By adding to much I was locking out my plant.
Idk, that looks like it just needs to be fed right? Long way from harvest.
Here, read through this. I use this to curb my overwatering and overfeeding tendencies.

5 Surprising Signs of Overwatering | Grow Weed Easy
by Nebula Haze This overwatered cannabis seedling is drooping from being given too much water too often. If you’ve got droopy cannabis plants, you’re not alone. Overwatering is one of the most common problems faced by cannabis growers. Giving too much water to your cannabis plants doesn’t mean...

Checked the pics again as well and it does have lot of white hairs for sure. Plant probably needs more nuts seeing between 4-6 i when they fatten up a lot and need a lot more nutes so i would add more PK during this stage.
But without more info it's hard to say really.
What week of flowering are you in?
What PH and EC are you using?
It is 47 days into flowering . About 65% of the hairs are orange, If you look at the whole plant. I'm really only feeding it one tbsp. of Fox farm big bloom fertilizer at this time . I cut out a lot of the nutrients because I was over feeding it and I was hoping that the leaves would un-claw and turn lighter green but they didn't. I guess that's not the way it works. My Ph is 6.5 let me know if I'm forgetting anything.

PH is at a good level which tells me it's not the nutrients, it's a deficiency. The leaves yellowing from the bottom indicates that the plant is cannibalizing the lower growth. Here is a picture of my plants after a normal flush. The fan leaves all simultaneously turned yellow on two plants. Honestly, it's up to you whether or not to keep feeding it, it will probably finish okay as it is but the buds might get bigger if you can correct it. You could try to correct it with nutrient suppliments according to the chart I sent earlier or a similar one and then use a flushing agent (like Flawless Finish) in the last few weeks before using pure water.

Updated that last post a bit for ya, flawless finish is good stuff!
It cant hurt to try to correct it, i guess. Ill try it

Just be careful not to over correct, plants are very sensitive to burning in flower. Use less nutrients than a normal feeding in veg.

Do you have an EC meter? This way it'sa lot easier to see where you're at. I'm currently in week 4 of flowering and i'm at 1.5 EC. Yours is probably a lot less and that's why it's taking the supplements from the bottom leaves in order to feed the top.
I don't have an EC meter but I'm planning on getting one. Just don't know what one to get. Do you have any recommendation on EC meters ? I think EC meters measure parts per million but what does it measure exactly. I'm new at this.

EC is electrical conductivity. And ppm is parts per million. Different scales measuring the same thing, the strength of your nutrient solution based on how much dissolved salts are in it.
Amazon has a cheap one for about $13.99 and should get you buy for your purposes.

EC meters are a fight on here usually. You can get by with a cheap one for sure. I like the Com 80's for around $40. Bluelab is over $100 but it's one of the best. I bought a second Com 80 last month just in case my 3 year old one dies. Once you get one you'll wonder why you waited.
