Hey everyone newbie to the site so I’m about 4 weeks into flower give or take a few days I do living soil try to get my ph around 6.5 - 7.0 most of the time in my other grows I don’t even ph my water and don’t usually have any trouble only issues I run into is too much nitrogen heading into flower, but this time it’s different it started off looking like nitrogen deficiency which I know there is plenty enough in the soil which makes me think I have screwed up somewhere with microbes not keeping the ph good in the soil, and it’s slowly getting worse I have given more organic nutes and thing’s steadily to see if their is a change and also dimmed my lights thinking maybe the led are burning the plant any help would be greatly appreciated because they are going to be awsome 🌱 and it is the worse time for me to get problems

Im no expert but with it affecting the older leaves i would say you are losing N due to overwatering . if it was too bright i think it would affect the higher leaves, and if it was nute burn i think you would see even tip burn over the whole plant.
we all have individual ways of growing but I would have had them snipped off a couple of weeks ago, especially the damaged ones , you dont want to waste the plants energy trying to repair them , and they will be cutting the light off to them bud sites

Thanks yeah I can’t figure it out it’s so frustrating I’ve never had this issue before so troubleshooting it is a pain not something I need this early in flower all the leaves are praying even the bad ones so it’s very interesting as to what exactly it is other then that they are going awsome best grow yet for early bud stages

The light makes them look a lot worse and like green then what they actually are and I water with rain water

Also 🌱 had no trouble through veg every thing stayed the same only thing that changed was I turned my lights up to 100% when it’s only been about 40%

yeah the fact they are praying makes me think its a bit of both , slight overwatering and the plant getting rid of leaves it doesnt need anymore. as your in soil you could let it dry right back ...till the leaves droop . i was reading a post on here yesterday from someone who says this actually makes the plant stronger , a bit of drought stress, and some people think it produces more tricomes.

that increase might have upset their 'equlibrium', i did exactly the same think on my last fantastic looking/smelling grow , 2 weeks before the end i lowered my light 2 inches and upped it from 80% to 100%, thinking it would give it a little boost, and the light stress caused it to throw up new pistils and some nanners, terpene production stops and the smell goes away.

tried this when had similar problems with overwatering in the past and it's worked well :)

Oz,

I think part of what are seeing is a natural aging senescing of an annual plant in flower. Doubt any fertilizer will make a difference now.

Thanks for the help guys appreciate it il chill off the water a bit turn the lights back where I had them and see what happens , the only other thing I thought was maybe I didn’t have quite enough nitrogen for the stretch because that’s about the time it happened after the stretch .
