That’s a sign that she is struggling to process phosphorus. The kind of burnt looking yellow tips that aren’t really burn are from struggling with potassium. Those are both mobile elements. When they show up at the bottom of the plant and in the older leaves, they are usually just hungry. When you start to see it on the upper part of the plant with healthy leaves at the bottom, it is frequently a lighting intensity issue that is popping those deficiency symptoms in the upper canopy. What is your lighting situation like my friend? I might back them off on the distance or the dimmer just a bit and see if you don’t see some improvement. Good luck. Cheers.

Very good Herbal! I was about to write the same. Lacking PO a plant cannot process the sugars from photosynthesis so it stores the fixed carbon as a carbon dense pigment, like anthocyanins.

I think it’s genetic.

I mean, it's living soil and with the compost tea I would assume it has everything it needs

Never assume in science.
Take measurements and listen to your plant.
Flowering plants are hungry and not all "no-feed" soils are built the same.
Feed it some PK Spike alongside a vitamine B product to reduce the stress it has gone through,
making sure you get a healthy amount of run-off,
and you should see it bounce back on track pretty quickly.
Vitamin B plays a major roll is de-stressing, just as it does in human biology.
Sometimes in these cases the deep colouring can be solely caused by stress.
Note: pH imbalances can block out specific nutrient uptake.

This is happening to my veg plant too. I checked the soil pH yesterday and it was in-between 6.5-7.0. Any recommendations for PK spike?

DR.PNW said:

No PK for veg.
Standard growth fertilizer should be enough.
Pk Spike by Green Planet is a great liquid PK, a cost effective powder would be Big Bud, Monster Bloom, Bud Blood, etc.
Organic PK would be more commonly a premixed top dress bloom food [1-9-5, or similar].

I suspect there is a stressor causing your plant to darken unreasonably.
Find the stressor and use B Vitamin to help recovery [Vitathrive is great, as is ThriveAlive].
The soil pH is on the high end but not enough to cause pH lockout.
Check your 30% run off PPM; 800-1200 ideal [strain and climate dependent].

Note: this could also simply be credited to genetics and could potentially be either; normal, or caused by a genetically predisposed sensitivity.

Damn! All these decades of using vitamin B1 for transplant, shock has just been baloney! What a marketing coup!

I hear everything you are saying and I am taking it in but I am started to lean towards genetics because looking at the girls today it is almost every stem is turning purple, even on the plant in veg and they are both Blueberry. I have not been watering until run off because of the living soil, I did water until runoff at the beginning but advised not to water until runoff with the living soil. I have been watering every 3-4 days exactly half gallon at a time but I don't water again until the top 2-3 inches of the soil is dry and I also pick them up checking the weight. My veg plant seems happy and thriving but the flowering plant looks sad about half way down. Although, the flowering sites are a little more dense every day. Just haven't seen much growth since she started to flower. Maybe an inch or two in the past couple weeks.

Note: These girls were stunted a little due to a late transplant but they bounced back real nice just haven't seen much linear growth once it started to flower. The veg plant is getting taller almost as tall if not taller now than the flowering plant.

Watering without run-off takes a high level professional approach involving regular soil samples testing for micro/macro elements.
Less run-off in living soil is okay, but should still be at least 10% if your mixture porous enough, ie. contains enough drainage medium, perlite etc.
30% run-off will give you the most accurate results when testing run-off for pH/PPM.

**I believe you are of the right mind that your genetics are more colourful, but try not to rule out anything else without some effort and trial**

Think about it Dr., it’s not proven science. Send me the ordinal research articles that demonstrate exogenous Vitamins, VBs, actually cause a beneficial effect. If you add this stiff and believe it works then use it. It does nothing. Have you Dr., performed controlled plant growth experiments with good controls and decent analytics to demonstrate the benefit. No.
