What does this look like ??

I got some soil plant going. I transplanted them to their own pots about 5 days ago. I am using cfls. The last time i checked the ph (when i re-potted soil) the run off was about 5.7 and they are about 6-7 weeks old (small huh?) all of my baby are doing well ,the bottom couple of leaves are yellow but other than that no problems, except for #3. The bottom leaves are yellow yes, but there are also dry brown circles on them. Anyone have an idea why?

1# sick plant, #2 sick plant, #3 & #4 somewhat healthy plants

Thanks

Well, your pH is too low (acidic). For a soil grow, you want to shoot for a pH of 6.8 +/- 0.2. I would say that the visually depicted problems combined with the small size for a 2 month old plant are very likely the effect of your pH. If your soil pH really is 5.7 (as opposed to just the runoff), then your plant is not able to take in the nutrients it requires.

I would recommend flushing your soil with pH-adjusted water (of about 7.0-7.5) until your runoff reads around the 6.8 mark.
