A few of my plants have a few lower big leaves like this. Rest of the plant looks good but I don't know if this will get worse. These are 4 weeks into veg. Feeding with sensi pH perfect A and B also B52. Under 2 1000 watt lights. Temp is 75 constant. Also the other small plant was from seed and is 2 weeks old. Please help.

Looks like a MAG deficiency to me. Get some Cal/Mag and it should help...the other 2 pics look like over watering. I also think you started feeding to early, as also has some nute burn..usually dont start giving nutes until week 4 never earlier. whats your runout ppm at?

How close are your lights, and how are the top leaves? what kind of soil are you using? it shouldnt be ph, AN usually buffers the ph , it could be lots of things, can you get a pic of the over all plant, also since your using soil you should try out molasses work VERY good for soil check out my outdoor grow , it has mag in it also sugar for carb, like bud candy... if your using tap it has calcium in it already

They are not into flowering yet. Still in veg. I use the sensi pH perfect so pH I'd constant 6.

I am using pro mix soil. The rest of the plant is pretty nice. Mostly all green

your last pick looks like Nute Burn, heres a pic of one of my plants catching early signs of it http://i924.photobucket.com/albums/ad89/slymaster/BrownLineLEaf.jpg Nute burn usually starts at bottom and works its way up. In the Late stages of nute burn you see white "Powder" like substance on the leaves before drying them out. It looks like your last pick is in the late stages. What you want to do is try Flushing.

This salt burn is common with soil mixes and yes it will get worse. Also its overwatered. Next time use coco.
