Have a 2 fast 2 vast that I grew for first time and she's showing spots. They were first Rusty spots on a green leaf now the leaves turning yellow and spotty. All during the beginning of flower.
Spots on my leaves. ..help I'm confused.

Jupiter- Looks like a few things going on here,... tell me what medium you're in, your nute'/feed dosage/schedule, if you've done any pH testing of medium, adjusting of nute pH,... Symptoms have a mixed look to them: P defc., K defc., maybe Ca too, hard to say,... PK demand is elevated now, in early bloom,...
Yes--been there. Looks like mid-flowering PH issues.
I would tease them along for a few weeks. A flush will only set them back best to get them to ripen asap.
The affected foliage is challenged and will not recover.
Don't be discouraged for it is part of learning via old school.
You will still have some good bud. I have had dozens of ph compromised grows. Soil indoors was real tough and recommend soilless after a few soil grows. Soil grows remind one of how we are shortening/compressing cannabis' natural grow cycle. Often with autos--the soil indoors is not alive for it takes a few months for soil herd to assist in feeding roots etc. However--the same will occur in soiless media if PH goes bonkers. And--I might add--have had PH issue with soilless by not following----manufactures recommendations.
Cheers

So I'm running all roots organics in roots original soil. My pH is usually 6.5. I'm pretty anal with the pH because I know the issues it causes so i ph my water also. I only did one veg feed within EC of .5 and that was about when was 21 days old. I did add the Humboldt big up powder with the organic nutrients but I took out the bloom booster. PH was 6.4 EC was 1.3. That was exactly 7 days ago. The Humboldt is like 33% phosphorus 23% potassium . I haven't tested my run off yet but I will tomorrow because I am due for a watering. My feedings are also a little light due to the fact I'm afraid of lockout or overfeeding.

Waira Bloom is.5-2-1 @15 ml a gallon, grow 2 -.25-1.5@5ml a gallon, hp2 is 0-4-0 @15ml a gallon, hpk booster is 0-5-4 @ 10 ml a gallon, and a kelp extract at 0-2-2 @ 5 ml a gallon up to the last week. There is also a bio catalyst at .1-.5-.25 @ 15ml a gallon. This is the Bloom feed. Some of the numbers go up slightly as the weeks progress. Let me know what you think if it's enough or not. Much appreciated.
Jupiter---all my soil grows looked like yours, but--far worse (and hoping all photos have been deleted with prejudice) and I too was using Roots. Tough to get PH set. So hot is the soil and then adding nutes just defeats the purpose. Normally--outdoors a grower will only feed if a def is noticed or last part of flowering.
Good luck--sounds like a great plan.

I used to feed a lot during veg and I noticed I would always have these problems. So I cut down to one feed Midway through veg and that seemed to work. In bloom I would go really light and that also worked but sometimes with new strains I get those damned spot. I do feed every week in bloom now I'm thinking I should cut it down. It seems after I get the deficiencies I do what you said and push through the cycle and the buds actually turned out pretty damn good . However I'm trying to get a hundred percent out of the plant so I really know how the strain performs . I just want to really push the plant to get those fat buds. That's why I actually substituted a synthetic booster to see if it would work. You see the results up top LOL. It's definitely a learning experience and I just want to know what is going wrong so I can correct it. Like a fundamental understanding so I can identify, diagnose ,and correct the problem. Thank you for the input much appreciated.

... thanks for the info! Hmmm,, you mean the in-soil pH is 6.5? How do you take you pH, with a quality probe (skinny probe cheapie models are lousy), or using the run-off method? The latter is a dubious method for accuracy unless you follow a specific procedure; testing straight run-off, especially after feeding, will not give accurate results,... here's a link-- ( https://www.autoflower.org/threads/...-for-run-off-testing-and-ph-estimation.41733/ ) ..... Okay, the Humboldt Big Up, it's (?)-23-33 ? Did you dilute? 1300EC, doesn't sound like it,... This may change everything,... I'm trying to see if you actually have a toxicity issue, and/or an off pH lockout issue, so that's why I need to confirm a solid pH soil reading 
... info for toxicity symptoms is pretty scare compared to defc.'s! Plus, they occur with other related issues at the same time, making diagnosis difficult,... Root original tends to lose it's lime buffering quickly from what others report, contributing to further pH drift,...

I'm testing the run off today. My nutrients solution is 6.5. When I do test my runoff I usually will mix up 5 gallons of 6.5 water. I'll water to a slight runoff wait a minute then put a little cup under my platform. I then water again until the cup is full for a sufficient sample. The Humboldt I follow the instructions. I added it with my normal feed but I took out the bloom booster I usually use and substituted that. Probably wasn't a good idea. Do you test your run off all the time or just when there's a problem? I use a blue lab pH /ec pen... thanks for the info! Hmmm,, you mean the in-soil pH is 6.5?

... check out that run-off testing and calculation link, mate... it calls for un-pH'ed water to moisten it up, the the final pour to collect run-off calls for RO/Di water, zero hardness,... anything you do to alter the pH will skew the run-off pH,... You did the right thing skipping the HPK! All these symptoms, they started soon after using the Big Up? As a synthetic, it's readily available right off the bat; organics usually need some time to be broken down by the soil herd into absorbable forms,... So, with that input, I wonder about it being a defc. issue, unless it's a lockout situation, meaning the nute's are there, but pH is off enough to render then unabsorbable,... K is pretty robust in wide pH range, but P get's pinched at mid 5's and over 7.5,... More likely, it's toxicity, but again, that's harder to diagnose, especially when symptoms are this advanced,... I don't see the usual tip burn associated with this either,... That pH is key at this point! And if it's toxicity issue, maybe pH as well, a true flush is called for, and doing that r-o test will be going down that road anyway,... In soil, I test for pH all the time, but I use an Accurate 8 soil pH probe, because I dislike the r-o method for several reasons, as stated....another problem with it is, you have to saturate the soil each time you do the r-o test, something the plant does not like, at least not for long,.. roots start to suffocate after 20 min or so, something like that,... no O2! Flushing is done fast as possible because of this, using about 2-3x the pot volume of water, less if it's a minor problem,...
