Watering around 6.0 @500 with roots organic vege stuff, nectar soil, was under LED just switched to Mh today. The bigger is a re-vege and the smaller from seed. Thinking two different problems here, maybe the same?
Yeah pretty well, nothing obvious, what would cause the color change?Have you scoped for bugs?

Could be colder temps for sure. Cold (and stress) can lead to a buildup of anthocyanins. What's the room temp?
That also looks like it could be a phosphorus deficiency, either from a lockout from ph or mineral binding.. I'd do a slurry test and see what the ppm and EC is in the soil..
Yup, 6.2 has been my sweet spot and what has worked for meIn this case I’d flush the soil with ph 6.0 water until you get to about 6.4-6.5. Hit it with some high P bloom fert with some added epsom salt (1/4-1/2 tsp) on the final flush. Let it dry out and then feed it normally.
You will want to ph your solution to 6.0-6.5 from here on out.
They like a little higher ph in bloom (flowering) and a little more acidic in veg. I hang out in the 6.0-6.5 range the entire grow.
About 7.5 from tap. Adjusted to 6.0. Pretty clean at 100ppm from tap.Are you using tap water? if so what's the alkalinity?
