Help my sick chick w/pic

Can you tell by the pics, and info below whats going on with this girl?

Purple Kush clone, vegged 1.5 mos. under cfl/T5
Topped twice, supercropped, and lst to grow all mains horizontal.
FFOF and nutes. No nutes during veg, I let the soil feed her.
12/12 under 250W HPS
First started seeing light green leaves soon after starting 12/12. Went from light green, to almost yellow, and finally yellow.
Then leaves started getting brown spots.
It's all over the plant, kind of random. Some leaves seem ok. New growth is nice and green, buds still forming, although growth of limbs is slowing.
Only showed pistils 13 days ago. 3ish weeks in 12/12 as shes a clone.
First 2 pics are 5 days into 12/12 when the lighter growth first started. The rest are 8 days later.
I've fed her nutes as well as molasses, very small amounts. 1/4t gb per 3L water 1/3t molasses.
If this is some sort of ph lockout issue, which im thinking it is. I use test drops for ph, so i know, i need a meter.

in the first couple pics, it looks a lot like nitrogen deficiency

its normal for marijuana to turn yellow during flowering becuz all the nutes are going to the buds. add some veg nutes and she'll get better

u can test ur runoff to get an idea of the ph
but it looks like u need to give it flower nutes....those last pics look like P def
check the ph first though cuz u could have the nutes in there ,just locked up

Will do, really havent fed much flowering nutes yet. but ill test runoff tomorrow. Hope to have a digital tester by then. Thanks a lot all.
Any idea on the brown spots?

Yeah little brown spots all over some leaves in the pics.
Got my meter today, had to soak it over night. I ph'd as close to 6.8 as i could with drops and flushed with 5 gallons. Fed some Big bloom, and next watering, ill have my meter calibrated and be able to start feeding flowering nutes phd correctly.
Runoff was around 5.8-6.0 hard to tell with those drops in cloudy water. I'll be able to check that properly also.

I am thinking that it could be stunted due to all the techniques you are using. Topping and supercropping could of stunt it enought to de-color and slow.

I dont think thats the problem. True i did top twice, supercrop and lst. I let her recover at least 7-10 days between both toppings, as well as the supercropping. As for lst, that wouldn't do what this plants doing.
I can already tell, having calibrated my meter, my Ph is way off in my flowering nutes.
I flushed with 6.5 Ph water until the runoff was clear. Ph is still a bit low on the runoff, but with the meter, and Ph corrected, i hope i have the problem somewhat under control.
I can say after flushing, she's not getting any worse. All the leaves that would come off at the stem, i removed. (All dead, i never remove a leaf if it doesn't pull away easy from the stem).
I dare say the buds are starting to fill in and take shape. Looks like 15-20 nice buds growing. For sure 3 mains, maybe 4.
I'll post pics later next week.

You got phosphorus def for sure...get some bloom nutes into them

Yep you totally need to get some nutes into them. You will be suprised as to how much they need.

I introduce the flower nutes gradually over 1 - 2 weeks once 12/12 is initiated and am definatley at the manufacturers recomended dose if not higher by the 2 week. I also do the odd plain watering as well. This is a soil grow by the way.

Lack of nutes and over nute can have similar symptoms on the plant leaves, beef up the nutes and I reckon your sweet

Thanks,
I usually under feed, but i think this was a ph issue more than anything. I started flower nutes, but i think i had the waters ph way off. (Too low)
After a 6 gallon flush of 6.8 water, and my purchase of a digital ph meter. I was ready to properly mix and feed my plant food.
I mixed up half strength Tiger bloom, as well as Big bloom and ph'd to 6.5. I just got done feeding. I tested the runoff, tested at 6.0
I think i'm back on track and will increse nutes as i go. As well as monitor runoff.
I'm gonna post some pics later.

They look really hungry to me dude.

Good stuff mate sounds like your on track with your ph. Give them full strength nutes next feed I reckon. Youll be fine

Well,
It's been a couple weeks since i got my digital ph meter.
Although the buds continued to sprout new pistils throughout the ph problems,
i did lose quite a few fan leaves. Some leaves that were slightly affected, seemed to take longer to die once i got the ph corrected.
A few leaves remain affected.
I never cut, or pulled a leaf unless it basically fell off to the touch.
Most turned very brown and crispy before they would come off.
In the last week or so the buds have started to put on weight.
My light (250w) is 11 inches from the canopy, which is very horizontal, and very even.
I think i had some light bleaching, along with the ph problems, so rather than fight 2 problems,
i raised the light to eliminate that and work on the ph.
Runoff is up from a low of 5.8ph to a solid 6.3.
Fed tonight 4L water 3T BB 2t TB ph set to 6.7
runoff tested at 6.3

Pics are a combo of yesterday and today some closeups with 5-15 loop magnifier.
Shes been in 12/12 for 5wks first real pistils 31 days ago.
Clone vegged 1.5 mos.
