Trinity yellowing after flip

[LostTribe]

Less than a week after flip under LED
RO
60ppm epsom(I have a diesel in there)
jacks 321
mr fulvic 1ml/gal
1.4 ec ph 6.0
68-77F
55RH

I was thinking Calcium and to add either cal nit of cal mag plus...I was under HPS in veg looked nice and green. Dripping 4 times a day until runoff in 80/20 coco perlite mix. I just started jacks about 10 days ago. Was running canna at 1.2ec with tap water and they were darker green, too dark.

that 68 deg maybe getting to it? Any cold air blowing on the root zone? Micronized Calcium might fix her up

Need more information.

- What is the medium? Coco? Hydro?

Just preliminarily - that looks like sulphur, maybe iron deficiency/lockout. Some non-mobile nutrient.

Sulphur

If you have a complete fertilizer feed then the yellowing is probably caused by the pH rising.

That's why I don't like using tap water because it can raise the pH with just a little watering.
