brown spots

[scorch]

67 days, so I would normally chop them in a week or so. I wonder if B and Q have changed the composition of their potting compost? I used to (almost) be able to grow without any added nutrients, now they start looking stressed at about 6 weeks.

So here we go again....
These are the next generation. Green-o-matic. seed put in B and Q potting compost on the 4th April. They looked extremely healthy until a week ago, and then the dreaded brown spots began. Does this look as though they have consumed all the nutrients in the soil and are needing a feed? Seems a little early to me. One of them is much less affected, the one furthest from the fan. This couldn't be some sort of wind burn could it? Humidty is a bit low, but no lower than it has been in the past. Ditto temperatures.
Doing a post mortem on the last lot, I'm pretty sure I have been in the habit of overwatering, as the root balls hadn't really extended into the bottom portion of the pot, I assume because it's been too wet.
Clearly I need to start paying attention to the garden again
