First grow improvisation RS11

I find this happens when over watering has been a thing and some root rot or some weird growth in the root zones is happening. Might need to amend with more perlite next time or dial in your watering habits. The yellowing of the lower older growth also does seem like it is not getting enough N. But the leaves should not be burning, twisting and collapsing into a thin folded blade. if all it was is N they just yellow nothing else. that is a key indicator to me its root issues maybe rot. Some of the spotting does look like PH but I would expect to see that on the whole plant not just some of the lower leaves.

looks like normal, because the are not getting direct light (: would not worry! adjust ph to 6.4 and feed some N 🌱💚

Hello mate, you have an issue with Ca/Mg caused by a pH fluctuation or a misfeeding of Calmag product. The first cause is often link to the rate of Ca/Mg in the water used to watering the plant, if you use organic feeding you must have the rigth rate of these nutrient that is 3/1 or 4/1. Good luck and happy journey!

Hello There- I would adjust your watering schedule. Frequent, small waterings cause root issues and lots of nute buildup in the soil. I think most of the problems you've seen on your plant in your diary are related to watering. For a 5 gallon pot, you should be watering (IMO) 1+gallon (or 4liters) at a time and then at least 3-4 days before the next watering. Of course...have to pay attention to the plant. Some get very thirsty.

More than one thing can cause that, so you're best seeing how it progresses. If mindflowers is right, that's either genetics cooler temperatures (68F or below) occurring at some point in daily cycle. If it's definitely red/purple coloring, then it's just genetics / cool temps. They look black to me, but photos are deceiving.

Looks like anthocyanins starting to color the leaf to me. Watching those plants like a hawk. as you should. looking good

no light = dead leaf solution = lollipopping 💚

The plant puts in the lower leaves that it is ready to sacrifice toxic elements or overdosed elements. Mineral fertilizers can cause this effect by forcing the plant to assimilate them even if it does not need them. It's normal so, there's no need to panic, the plant protects itself and manages the elements it accepts and those it rejects. 😉✌️

The 'red' i see may also be a camera illusion.. if you don't see reds or purples with your eye, nevermind.

High ultra_violet, There are a few signs from overfeeding and nutrient lockout. But you are almost ready for harvest so I would not do too much about it. You will harm more with trying to fix it then just let them ripen for the last 2 weeks. Happy growing and happy harvest buddy!

https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg Kinda looks like a P issue. But your also almost done so could be a bit of fade? Also the feed has lots of P in it so it should not be deficient at all. Bloom 4ml 12-36-12 / Boost 3ml 9-10-38 = 10.7-24.8-23.0 NPK ratio. Ton of P. almost to much. Your suggested feeding for the nutrients used is here : https://420flow.de/cdn/shop/files/FINAL_V2.png?v=1713467798&width=1000 This is also a good tool. https://www.nutriag.com/wp-content/uploads/mulders-chart.jpg Its shows high P requires High Mg as well and can make issues with Ca. I would monitor the EC of the solution and back off some of the feeds as it nearing end of life. Also do any of them feeds say their micro content? Eg. Fe, Cu, Zn, Mo, Mb,?? Also you are getting a good amount of runoff when feeding them yes? if not it could be a build up casing issues.

It is absolutely normal for late stage flower to develop dark colors in the leaf. A lot of places are actually breeding that into the plant because it’s turned into a desirable look. I did a quick search for the RS11 plant and it looks like the majority of all the end of flower plants have a very dark purple leaf. I would say you are right on track and keep doing what you are doing. It should turn some lovely color by the time you are ready to harvest. Hope this helps.

Make sure you don't let the soil dry up. Any minor NPK needed will be taken from the leaves.

Hmmmm. You're in ripening so as I said I in my other reply to your leaf issue. Lower your light strength and you can even higher it and it'll help ripen a larger surface area. 30cm away is for heavy floweinh you should be using 80% and dropping it so as this stage I'd say drop it to 60% and higher it a bit.

High ultra_violet, No it is not ready yet you should wait another week if you want to harvest the plant at her most potent. The orange trichomes you see are not on the buds but on the leaves. They are orange waaay before the buds. I personally like to trim from the moment I chop the plant. The cutting is just easier then when you let it dry first and you prevent mold a lot better when you cut before drying because the moist can escape a lot better. Happy Harvest Buddy! 💚

Yeah as others say, it's getting to end of life stages. Just carry on as you are for the final few weeks.

This is just growing stresses. For it's stage there's no point in saying anything about defs/toxs. As at this point. You're in your final days If you've a loop or Marcocam. Look for mainly cloudy trichomes. If you see amber in spots. It shows its fully ripened. Your buds are HUGE. as your in ripening now. Less light is needed. Lower your light to 75%- % of its main power used and keep lowering it the more it ripens. Ppl use less hours also. But them folded leaves are signs of stress from too much light. But, as I said.with the stage your in just push on and as things are, they can't be changed. You got good buds, so 99% the chances are the quality will match what you're seeking from the strains in

High ultra_violet, othing to worry about buddy she is almost (1 more week) ready for harvest! Happy Harvest Buddy! 💚
