Is this from overwatering

It's only on the first set of serrated leaves. Its neighbor shows no sign of damage. Bag seed, 9 days old, in a peat pot with the dreaded Miracle Gro, under daylight CFL.

possibly....

I'm not an expert (in fact I'm most definitely a novice) but that does not look like over watering to me. I could be wrong.

However, mine showed nearly identical damage on that first set of leaves. A month later and they're fine. Rather than trying to retype everything, here's a thread about what I did and did not do from another board: International Cannagraphic Magazine Forums - Week old plants develping brown spots on leaves. Help. (pics)


This pic is how they look now:

Thanks. I didn't see what your final solution was, or if you just ignored it and it got better. I plan to get a pH meter tomorrow. But I don't think my pH is too whacked based on my last grow, which was my first. This plant and its neighbor were definitely in a too humid environment when they first sprouted.

Don't know for sure. My suspicion is it was the nutes in the Sta-Green soil I started with. Of my three plants the only one that did not show that burn damage was the one that was never in the Sta-Green. Hmmmm.

I never really ignored it, per se. But I was wary of causing three or four problems by trying to fix one problem. For the most part the new growth was healthy and vigorous so I mostly stopped worrying about it and just let them continue to grow. It's seems to have worked out fine.

Might be the nutes in the soil

dude , that could be lotta stuff, but my guess its a nute problem, either a K deff or an overnutting problem, u should know what uve been doin with em so get da best outta the responses u get
