Late Flower: Lower Leaves Yellowing and Purpling/Clawing

[Jumfrey13]

All the plants are like this just as the title says Here's the lowdown:
Medium:Roots 707
Nutes: GO Biothrive Bloom and CalMag, light yucca extract, brewed for a day. (I have only recently started feeding a light nuts solution. Main problem is, I don't even have the full nute line).
Temps are fine
RH is fine
I am assuming my main problem is not having the full nute line. My question is, what should I do to supplement that? I have a lot of stuff I could till into the topsoil. I have all the down to earth products on hand, sea bird guano, bat guano 0-5-0 and bat guano 0-13-0. I have a lot of things I could use on hand. It looks to me like the purple coloration is from phosphorous deficiency and the yellowing Idk. Any word on what I can do? They are probably a little over two weeks away. All organic.

Wow. Yeah, that's gonna be a tough two weeks from the look of it.

You say you're feeding lightly... what's your PPM or EC, and what is your PH? When you say you only recently started feeding lightly, I'm sure you're not saying you just started feeding them, period - does that mean you just recently cut back on the feeding? If so, how much were you feeding before, how recently did you cut back, and when did this start happening to your plant? What nutes were you feeding earlier; you couldn't have gotten all the way through veg and this far into flowering with what you're describing.

What does the rootball look like? Have you pulled the plant out of the pot to see? How long does it take to dry between feedings?

How often are you watering? I think you've got a lot more going on here than phosphorous - I think you have a multi-nutrient lockout or deficiency, and and I'm trying to get a sense of how it got to this point. In all honesty, if you're this close to finish there may not be anything you can really do about it but give it a flush, a light feeding schedule, and hope for the best.

Have you given any micros at all? Like for boron, sulfur, molybdenum etc? It looks like you have not to me.

I have not fed them micros for quite a while when i ran out of kelp meal. ;(

Thank you for your concern. To be honest, i was only feeding with BioThrive Grow in the beginning and top dressing with alfalfa meal and some neem seed meal. I went into flowering and still didn't have the Bloom formula so i fed with biothrive Grow for the first three weeks. Then i finally bought Bloom and i've only been using that and GH Calimagic. I have topdressed with 0-5-0 bat guano and some kelp meal in the beginning. I ran out of kelp meal though, which could explain the low in micro that @hotrodharley mentioned. I never checked the roots in the pot. I have to upgrade a lot of stuff. I bought the full nutrient line from GO and it should be delivering in the next couple of days. I have a bottle of Maxicrop, which is liquid seeweed. I wanted to use that to get some micros but a lot of people have told me to throw that stuff away, that it will damage plants. :/

For the pointer. I have just recently started feeding heavy nutes, but I only had the biothrive bloom, so it guess that I was giving a lot of macros and no micros. For a long time, i was only feeding them teas and trace amounts of biothrive grow. I was flowering vefore i even had bloom nutes. It only recently started looking like this after I started feeding them heavy. Im going to tea them up next and then I will see if they green up. Then I will use the whole nuts line and see if that works better. I'm sure it will.

You DO want to feed veg nutes until about the 3rd week of flower at least before switching to bloom mode.
