What's wrong!?!

Plant is an auto about 2 weeks into flower probably. Just got back from being away for over a week and saw just 3-4 sets of leaves that look like this . They are located on the very bottom of the plant. Not sure what it is as this is my first grow. The rest of the plant looks healthy.

For more details on my setup if that helps answer the question see my grow journal

Should I pull these off the plant ? The lowest set I pulled 1 off each plant as they were practically dead but these are like half dead so wansnt sure if I should just leave them

No one?

The lights off plz. My guess is that it's hungry, you were gone for a week, so it's pulling stored energy from lower leaves.

I'm still vegging and I have to water every 3 days feed every other watering

I have basically the same watering schedule as you but since I missed a week of feeding should I feed extra next nute feeding or feed a lighter dose onwhat was supposed to be my plain water day?

Also this is an autoflower. Any idea on nute strength? The last feeding on this past Monday was at 1/2 strength . Should I up this to full now?

Also just realized when I feed them I'm cutting the dosage by half and putting that amount in a gallon of water that I then use to water both plants. So is this then only really a 1/4 dose?

There is too much nitrogen in the medium, look at the color of the leaves. Autos are very delicate plants, extremely sensitive to nutrient, even an insignificant overdose will lead to allot of problems. Autos should not be given any fertilizers unless visible signs of deficiency appear such as pale green color. My advice is to stop giving any nutrients or additives.

Only reason I thought it couldn't be overdose is that they were completely healthy before I left when I had given them nutes but when I came back after 9 days of just plain water they were dying on the bottom like this.

I believe the reason why this happened, because before you were leaving the plants were in the transitional stage. Before the transitional stage, plant uses allot of nitrogen and as soon as rapid flowering begins, nitrogen used in significantly lower quantity thus the concentration in soil was gradually building up to the point when it became toxic. Of course, it is your choice, but I guaranty, if you feed the plants with fertilizers the condition will get allot worse

So here are two more problems I noticed. The stems on the upper part are turning red . Also some of the leaves have this rusty brown spots
