Yellow leaves some green veins

[Jewbilee]

-Problem: bottom leaves yellowing
-Medium/grow method: soil;
-Feed and supplements used: ph perfect connoisseur a+b 2.5 ml/L each.
Calmag - 2.5 ml/l
B52 - don't remember dosage off hand
Bud candy - 1.5 ml/l
Cornucopia plant energy 3t/G
I feed by submerging air pots in container of nutrient rich water.
I was putting all those in them diluting down to about 900ppm. Was worried about lockout and was not sure what to do.
I have since changed to a water+calmag/water+macros/water+supplements rotation and it always keeps my ppm's under 900
-Water source: using dehumidifier water
-Strain and age short stuff auto purple amnesia haze
-Climate: pretty consistent 72 deg
- Light used: HID, t5 about 4 inches from tops. Just added a supplemental led bulb
-Additional info: How l went away last weekend. When I left Friday they were fine. Came back Sunday night they were slightly affected, and has progressed slowly over the course of the week
I have two plants, one about a week older than the other, the older one seems to be worse affected
The first picture is Sunday, the rest are this morning.

They are finishing their third and second wins respectively

Are you hid lights that close also?You should raise lights to 20 to 24 inches so she can stretch a little.Lights that are to close will cause plant to become to bushy and not allow side branching to develope like they should.I would remove the worse yellow leaves,raise the lights and see if this helps.

Hid was a mistake, left over from the template. I have a 2 ft 4 bulb t5 and a small led.

-- what's the cornucopia stuff? ...symptoms look like N defc., odd since there's plenty going in,...maybe too much at 900ppm at least initially, but I don't see signs of nute burn,.... what soil is this? A pH check, in-pot is called for,... AN "self-buffers" only in solution, not once in the pot,... Lights are too close regardless, this may account for the compact build as Nammy mentioned,... If you grow in soil or soilless, a wise thing to have is pH tester for direct measurement,.. the Accurate 8 soil pH probe is a good choice,... meantime, the only choice is a run-off test, crude, but in that small pot and the method you used to feed, it may be helpful to do a simple water only check,...best with RO/Di water, something low ppm,... water well, let it sit, then add enough to collect enough run-off to test both pH and ppm's,... that will offer some clues....
