Leaves yellowing and dying

[Dryxi]

I went on vacation for a week and come back to the plants looking yellow and dying. All the fan leaves are yellowing. I am growing all organic notill in BAS soil. They had enough water in the res and werent showing symptoms like this before i left. Not sure where I went wrong to cause this or how to fix it :/

All help is appreciated.

4x4 SIP planter bed. I don't ever ph my water. It's tap and filtered and the plants are 42 days into flower. I don't do bottled nutes or anything.

Have you checked under the leaves for bugs? (Pics 1&3)

 

[Dryxi]

I can't see any evidence of bugs at all. Nothing on the leaves and nothing under them either. Is it a defenciency?

Are they salvageable? Not supposed to be done until 10 weeks and they are currently at week 6

Looks mainly in the mid-section. Add Phosphorus and potassium.

What amendments do you think I should use? And how should I go about getting it in the plants? Just topdress with some EWC?

I would think liquid kelp if you can get it. I believe EWC is time release.

Do you think they are salvagable? I will get some liquid kelp asap but if not salvagable, i might save time and electricity chopping and starting over...

Myself? I'd try the kelp. Aerate the root zone with long thin probes or skewers. It will not hurt the roots. Deep. As deep as you can run it. Then apply your feed with kelp.
