New grower, not sure what is going on, but it's getting worse.

I have 2 plants in about their 4th week of flower. One started turning yellow and now the leaves are dying. It looks like the other one is right behind it.

I'm growing indoors under 1k HPS lights in a tent. Using Roots Organics soil and I water with the Roots Organics schedule... fert day, water day, dry day then repeat.

I started growing very recently and only have one round under my belt. I've had an account here for a while and have been lurking quite a bit, as well as reading everything I can. I've seen those charts with leaf images, none sound exactly like my problem. I'm wondering if they've caught some kind of pathogen?

The first plant:



The second plant:

TRy to take a week off from feeding to see if thats the problem, just flush for a week.

Looks like they need nitrogen man i keep my babies about as dark as like an army green. not extremely dark but not too light. if they start to claw downwards really bad stop the nitrogen immediately. looks like one might be cal deficient as well or ph problem i see some brown spots on your second plant.

4th week in flowering...that might be normal if this is an 8 week strain but I could be work. Get some cal-mag.

This looks normal to me... just make sure any new growth isn't doing that, and pluck those brown and yellowing leaves....

some leaves WILL die, and that one proly just wasn't getting enough light...... You're doing fine, don't worry about things like that .... if new growth comes out looking like that then start to worry, but as it is I think you're fine.
