Ph in the soil is 6.3. Ppm is 1000. Light is 100w at 35% intensity. Rh is 1.5. Humidity is 52%. Temp is 76.7f with lights on and 70-74f with lights off. Not quite sure what could be going wrong. Watering a gallon every 2-3 days. Any insights are appreciated!

What week of flower are you in? I used to get this when I would switch my nutrients from grow to bloom the moment I flipped the lights to 12/12.

Since then I've learned it is better to do a grow/bloom blend and feed that up into week 6 of flower then go straight bloom. The reason for this is that through the stretch and flower formation period the plant needs a lot of Nitrogen to build up all that cellulose. If you aren't doing this then N tends to run out in week 4 - 5 and you start to see this happen.

Could also be a cal/mag deficiency. Are you supplementing any cal/mag?

Yeah I'm on week 12 flowering and I'm using cal mag along with
I've been using all 3 at the recommended dosage. I also have worm castings but I wasn't sure if I should add that while using liquid nutes

If you are in week 12 then this is probably just normal leaf senescence. Basically the plant telling you that it is close to being ready to harvest.

BTW if you are using liquid fertilizers worm castings and other amendment inputs are not necessary. The liquid nutes should have everything the plant needs.

If you decide you want to try to use the nutrition in the soil and use water only, then you want to use those types of amendments prior to planting your plant so that it has something to pull from. If you are using one of the prepared "organic soils", they aren't really soil as much as amended coco/peat/perlite potting mix, then you can do what I do and feed the plants synthetic nutrients allowing the natural nutrients to back up whatever you may be missing.

Some people call it Synthganic farming. Having used this method, I have done away with deficiencies for the most part.

Wasn't sure if it was light burn, it's only happening at the top of the plant. What soil do you usually use for your grows?

I started to reply about the woes of late stage organ failure in the fans and then realized I was turning it into a grow diary.

I imagine some folks might think I'm full of shit but I found an off the shelf organic soil that keeps my plants fed through three months of veg with absolutely zero nutrient deficiency, just happy girls. I've not tried to see how much further than that they'd go, I just knew by time and size they had to be getting near the bottom of the chow bowl. If you ever want to play around with it, it's called EB Stone Recipe 420 Bhang. I was surprised it was available on the shelf at DIY here in town.

That's a bold claim but before I question it, how large a pot did you use the soil in?

I like to use Roots Organic Original recipe. Even though the mix is supposedly "organic" it really isn't. Most "organic" mixes aren't really organic.

Yea well that doesn’t seem to high especially for half organics just going off the burnt up tips and edges of your leaves normally means overfed just limp her to the finish line now bit late to fix anything now

That seems awfully small to go from seed to harvest. If the soil has been highly amended it would burn young roots. Not saying you're a liar but I can't think of anything that they could do that would be any different from the other companies that make amended potting mix.

Every amended soil I know of seems to peter out around week 6 - 7 at that size pot. If you had said 10 or 15 gallon then that would be way more feasible but, again, I've never seen a potting mix go from seed to soil without any amendments and only water except for when they are used in large pots.

If I can find some I'll give it a try but I'm skeptical..........

I’ve been using advanced nutrients for years
If u follow the recommendations on there website you will fry your plants like shown above^

I use hydro nd to get my ppms Within range of a 110L tank
I use around 1/2 to 1/4 the recommended dosing sits my ppm around peak flower no higher than 1200/1300ppm

At full strength with resting ppm 80 would come out around 2000/2200 ppm

If mixed well with the right ratios the ph perfect technology sits around 6.2
I set it to 5.8 nd let it wanted up only adjust if go over 6.5 (hydro)

The first thing I thought when I saw the pics was excess nutrients.

Also would u recommend limping it to the finish line as it was mentioned above or is the smoke going to be really bad?
