Possible deficiency with a (supposed) Columbian Gold landrace

I'm fairly positive I'm seeing a deficiency in my (supposed) Columbian Gold lady. She's extremely finicky and will burn if you look at her wrong. So I took my last attempt, re-vegged her in the same soil (I re-vegged mid flower as I burnt her too bad) except I added some extra Coco coir, plopped her in a new container and I've made it almost 3 months now with no issues. I knew I would need to feed her eventually, so this isn't a surprise. But it started to show in the matter of only days. My leaves are starting to slightly yellow, the tips are brown and curled up on the affected leaves, and I'm seeing a lot of red in the fan leaf stems. My temps during the day are 70-78 and my night time temps are between 60 and 70, which I know cold can cause this, especially with strains like this. I'm under a 600 watt hps. The soil is FF HF & FF OF with about 10% (of the total volume) coir and a half tablespoon of kelp meal. The kelp and coir were added before the reveg. I'm a rols / notill grower now, so she also has a clover cover crop. The planter she's in should be roughly under 3 gallons.
If I missed anything, tell me and I'll add it. I can take more pictures if requested.
I have a whole slew of organic soil amendments, including compost. So I can make a top dress mix or tea, depending on what it needs.
If anyone from the ROLS notill thread could give me some pointers, that would probably be best. IMAG0714.jpg IMAG0713.jpg IMAG0712.jpg

Can you take a pic. of whole plant, so we can see where the old damage is. It looks more like burn to me.

nothing needed my man no full sativa likes any fake soil that i know of . the old roots have trouble with calcium *OPINioN* not fact. i grow durban and a few haze crosses . they are used to hot soil an such , just let her do her thing and keep the calcium going. i use nettle tea but it has iron witch not all plants like (even in the canna family)

Pardon my ignorance, but what do you mean about the calcium?
I was thinking of giving her a seed sprout tea soon. Maybe some aloe vera too.
I have actually have some Durban and a Haze from Rare Dankness in the mail. I'm excited to see how they'll like my soil after I run my Yunnan in it.

calcium is dircectly related to ph and cation excange..... so if you have humis, fossil, shell, azomite (clay) and water you should be ok .... i use camomile foliar on mine at this point . tsp per gallon

Man I still have a lot to learn..
The soil probably isn't the best. It's just Fox farm with some coir and kelp meal.

It seems as if the issue is getting worse. I recently upgraded to the 600 watt (running at 450 watts) instead of a 150. So I'm pretty sure the additional light is exacerbating the issue as I upgraded about 14 days ago. Yes, I made sure to give the plant time to adjust to the light and still am. She's currently two and a half feet from the new light. There have been two nights recently where temps have dropped into the upper 50's for a few hours (damn this Midwest cold wave).

Wow what a training job. Maybe just a little stress?
Thank you. Everyone keeps telling me that. I just didn't know what else to do with her height.

Could be, not sure. She's always been very sensitive to nutrients but takes everything else like a champ. I had two clones that I took the first time I grew her out and stressed them to the extremes to see if it would be worth keeping around since it flowers so damn long; absolutely random light schedules, extreme training, super cropping, etc. The only thing that really affected them was hot nutrients and losing the majority of the leaves. Never once hermied or threw a nanner though.

The one thing that somehow we never looked at, PH. What have you been doing for PH?
Honestly... Never bothered to check it. I was actually wondering if that could be my issue. All of my ladies now, besides this one, are in an organic soil mix that I've cooked properly and I never water with chlorinated water.
I noticed today that it looks like she has a phosphorus deficiency. IMAG0742.jpgIMAG0741.jpg
But I really want to say that it's something else just mimicking a deficiency. So, thoughts on what to do?
