1st Week of flower: yellow leaves & spotting + white bumps on stem??

1 of my 3 plants (grown from bagseed) has problems. The bottom leaves are yellowing fast. A couple nodes up there is some brownish spotting on a few leaves. The upper 3/4 of the plant looks nice and healthy. The stem is bumpy as hell. It's got little white bumps like you would see just above the soil line, but they continue 6-8" up the stem and even 1-2" into side shoots. I've never seen this happen on any other plants.


indoors under HPS
FFOF soil, no nutes yet, recently repotted
runoff PH is at about 6.5

My other 2 look great. This one also got a lil sunburned 1st day under the HPS (18" away) while the others didn't. Temps range from 75-80 with lights on.

What could be causing this?

...since you haven't fertilized, and your pH is in range, I'd say you need to give'em some cal./mag.

Thanks. I'll look into it. I was leaning toward that type of deficiency, but I'm using tap water so I ASSumed there was enough in the water

How about that stem? Have you ever seen the white bumps that high on the stem?

Thanks
