Went on vacation and came back to this...

So I went out of town for 8 days and before leaving set up an auto watering drip system, but do to time constraints I only filled res with Ph'd water and set the schedule. I Fed the day before leaving and returned to quite a bit of yellowing from 2 of my ladies. And the 3rd seemed unphased.
I'm in soil and week 4 of flower, I've already fed them upon returning home 3 days ago but haven't noticed a chance in color. Any help is welcome.
The last photo is of my normal looking lady. Couldn't get the lighting right on her so the color looks a bit lighter than it is

Looks to me like they've been overwatered Maybe.

I thought this as well but when I returned home they were dry, I had it set to water every two days. And returned on the second day in that cycle, showing that they drank everything in between waterings

They starved for a week

Color won't change back to healthy green on the affected leaves but shouldn't get worse once you get back on track

What are you seeing that would make you think this?
Just wondering

How much and what are you feeding them

I hear what your saying, I'm just having a hard time with that one, for the last 5 years I've only ever fed once every 7 days. So she went a total of 9 days without nutes and this is my result?

I use meigs organic fertilizer. Been using for several years with WONDERFUL results. Feed 1 gal per week per plant and phd water every other day

I don't do soil/organics so can't comment on your feeding schedule.

It seems the most likely culprit is your drip system. It takes time to tweak things to ensure both consistent output and reliablilty.
I'd bet big that only the remaining healthy plant was being watered correctly.
The other two suffered

If its good soil why are you ph'ing your water and feed?
Im in soil and use NPK's RAW and never ph .. i just mix and feed..
What size pots are you in?

I dont ACTUALLY ph the water the water I use is pretty good on its own and then the soil buffers to around 6.3. I say phd because when all said and done the level is where it should be therefore its "Phd".

I'm in 7 gallon fabric pots. Usually use 10 gals but have done in 7 with no issues

I'm leaning on this as well. I only had a week before I left to get things going with the drip system. It uses soil spikes and im noticing they clog ALOT

Yeah im in 7's..
That ph thing you said had me wondering...

To me just from the pic (if no info was included)
I would of thought it needs more food. And by food i mean everything, not just N..

That is way past 8 days , but you ain't pulling my leg.

He's not saying 8 days of flower, he's saying they were fed just water for 8 days.

Brew your next feed. Add microbes & molasses. Lots of guys using organics treat deficiency this way. (I’m stoned, so get a second opinion)

And I'm saying that plant has had deficiencies for alot longer than 8 days

It was completely healthy the day I left on a Saturday. Beautiful green and purples. Then I came home the next Sunday and... yellow.... so confused

I have no reason to lie about their conditions lol. I'm not here to look good, I'm here for possible answers and solutions.. therefore it would be counterproductive to lie about it

Looking at your situation and thinking of my own experiences...they were and are hungry. Week 3 and 4 of flower in soil is when they have stretched like crazy and used a ton of their available nutes, especially N.

They need a balanced feed and a good boost in some form available by week 3 and 4...it has to be added ahead of time to be available at this critical time. So they won't be dark green but should be excellent all the same if you get on track.
