Leaves. Color - Yellow

Hi now first of all she's not gunna die so stop worrying so much. Yellowing leaves means she eating herself for nutrients now we use this to our advantage at the end of a grow with the flushing process but in this stage as you know its not good. The good news is she will recover if you give her what she needs. If you want to look at a similar problem I had then check out my Tropicana poison diary about 3 to 4 weeks ago i have the same problem and well look at them now. they are huge. and very green. A grower has said the leaves will not change colour I have found this not to be the case though this is nothing to be argued about because each strain is different. You never truly can know if its a problem or just part of the pheno. The breeders are not very descriptive when it comes to actually growing plants sometimes they will say certain characters of plants and other times they don't it just comes down to guess work and experience with each new pheno. So my advice up your feed considerably I suggest a ec of around 1.6 to 2.0 for plants this large. With that being mentioned the amount of feed you need is going to corollate with the size of the plant so larger plants are going to take more feed or higher concentrates than other smaller plants. Myself I try never to grow the same strain twice in order to maximize the amount of experience I have with each pheno. From my experience the way to tar all your plants with the same feed schedule is to constantly keep the plant with feed. though I do not grow in soil so this is possible for me. Unfortunately for soil growers the plants take quite a while to uptake the nutrients from the soil so even if they are there they cannot uptake it very quickly. This is all my opinion and none of it is fact. we all grow our plants in different ways and its one of the reasons we all love the grow diaries community so we can compare and share all of our growing experiences :) Great looking grow anyway and good luck for the harvest :)

Hmm it could simply be that your plant is in the final 2-5 weeks of its flowering so it's starting to eat up the Nitrogen in the leaves, which is completely normal. It could also be that your PH is off so it's not getting all the nutrients it needs. Are there any signs of decay or necrosis(dying leaves or parts of leaves), or leaves falling off often? I recently had a fungus knat issue in which they were killing my roots with their larva. It happened because I was not letting my soil dry enough which leads to bacteria or fungus growing in the soil, that fungus knats love. It looked like a nutrient or PH problem at first, but then lower leaves started to yellow and fall off rather quickly. Also, the new upper leaves were slowly dying and showing brown dead spots which would get bigger as the leaf died. Hopefully that's not the case but it's something to look out for.

I placed the lights at a distance of 30 cm(spider 1000) And I brought 75 out of 100% of their light. And I try to give them less fertilizer. Do you think these flowers are a good product? I think the buds are too small for week 8 Actually, today I measured the run off ph 6.7 ppM 800

Looks like u pulled back hard on nitrogen and so it's lighting up. Technically your plants can survive even with lol to no leaves and still produce buds in flower. I'd probably just keep going the way you are with no changes and then learn from it for the next grow. 🤘😤

It will not change color back to a "healthy green". Leaves changes colors a lot. But in flower generally speaking Cannabis will not transport/intake nutrients to leaves. The plant will translocate from leaves but the leaves are "done" growing and it uses it's energy/nutrients for making buds and keeping itself healthy. It makes sense when you think about it really.. It's Biology/nature.

I can help.. But your gonna get some weird info here from the internet so be careful about "google". The problem is... Your salt heavy or light.. Judging by the too much purple on the plants stems that leans towards salt heavy.. But your leaves being so yellow leans towards light on nitrogen. But I'd have to know more about your feeding practices/train of thought. Have you check the TDS and PH of your run off.. I see leaves are praying so that's a good sign.. Looks a bit stretched out but a lot of that is where your light is at/genetics.. Anything you put in from this phase on will go to Buds so generally I would discourage or lean people away from adding 2 much Nitrogen at this point. I'd say just go with a lower TDS feed like 800 PPM and let her grow.. The foliage will not Change color at this point.. If you oversaturate nitrogen she might get green again but she will also never use it up so generally speaking don't worry to much about the yellow leaves.. As long as they aren't dyeing off and getting crispy fast.. And if your overall health and vigor looks good then your in good shape.
