Hello guys. I have 14 Glueberry OG auto. Is this normal in flowering or is a lack of nuts? I water 2L every 2-3 days 1.8+1.8/L sensi bloom A/B +1/L carboload. They are 46 days old from seeds.
Lower leaves turn yellow day 46

Could be a combination of two things lack of nitrogen and it's moving it to new growth just because your in flower doesn't mean you don't need it, you just need less of it. Check the NPK readings.
Secondly it's not getting the light needed happens to alot of lower older leaves the no longer see substantial light.
Up your base nutes slightly see if it solves the issues. Watch for burn. Increase 0.1/2 ml a time. If your struggling with EC/PPM final figures drop the carboload dose slightly, or dilute with water 1/2ltr a time.
That said you could have lock out check your pH's.

I dont know how much youre feeding that monster, but it looks hungry. Has your ph swung lately? Plants that are feeding heavily can make your ph flux. Also certain strains are heavier feeders than others. That looks like a nutrients deficiency to me, but Im just guessing.

It probably is a nute deficiency. But having grown this strain multiple times, the leaves on her tend to yellow earlier than other autos I've grown
Medium is plagron light mix. pH is around 6.2. EC and ppm don't know
So I have to feed heavier? Right now I give them
2ml/L sensi bloom A/B
1ml/L carboload
1ml/L overdrive
4ml/L guano extract
You pH after your nutrients have been added and mixed into the water, right?
Please let us know what the labels say for recommended amounts of the nutrients (or just post photographs of the label on the bottles).
That's how they look after 2 weeks. I have a lot of tacoing. My temps are 25-26 lights on but maybe is a light stress. Does anybody know if too much light can harm them? My canopy is 6x4 feet and I use 1000 watt CMH in the middle and 2x240 watt quantum board at the rear.

Classic case of not enough grow feed during stretch when they need it most. Also switching to bloom feed to early.
Id make a mix of grow/bloom 50:50 for a week or so then move to full bloom.

Let's focus on one problem at a time, shall we?
We're discussing and trying to resolve a nutrient deficiency problem.
Yes mixed. I give them as they recommend.
I follow feeding schedule found based on the same strain. Thought maybe it caused from intense lighting.
I started them with bloom nuts. Never fed them veg nuts. Root juice and sensi bloom A/B from the begining
Well, there you have it. Bloom nutrients typically have very little or no Nitrogen whatsoever. Plants need Nitrogen throughout the entire life cycle, particularly during veg and early flower.
In veg I was feeding 5-4-8 started at 0.5ml/L and same feeding right now at 2ml/L until the first 3-4 weeks in flowering. Right now the eat 6-9-12
Your ratio in veg and first 2-3 weeks of flower should be a ratio closer to 3-1-4, and in latter stages of flower, about 1-1-2. Your veg and early flower nutrient regimen needed more Nitrogen from the very start.
You need to add more of whatever bottle has the Nitrogen in it. It will not fix what's currently broken, but it will stop the problem from getting worse.
Also, do yourself a huge favour. Buy an EC/PPM meter.
