lengthwise-curled leaves, with spot? any ideas?

    hey guys, i've been looking at the guides, troubleshooting faqs, etc, and i can't find any examples of what i've got goin on. so if i could get a few opinions, i'd love to get this little girl happy again.

    she's about 5 weeks old, and i botched topping her a week and a half ago (only one new stem is growing :( ). but new growth is all looking fine, it's just these sun leaves that are suffering. some are just limp, while 2 have curled under, lengthwise.

    my first guess was humidity, which is kinda high because i'm having trouble with my vent., but that didn't explain the spot to me. those tiny, tiny white spots brush off.. i think they're sawdust from my cabinet.

    help? thanks!

    Need more info, what type of soil, what type of ferts and how much/often, pH of run-off would be nice.

    soil is an organic potting mix w/ ferts (i know, that's bad!) 14-11-8. i'm feeding with 12-0-0 blood meal and 0-5-4 florabloom every 2 waterings. my ph meter sucks so all i know is ph is roughly 6. time for a new one of those!

    so, my best guess is the ph is bad. other leaves have some twisting mutations, don't know if you can tell from those pics, but i think i read somewhere that bad ph can do that.

    eh?

    ph of 6.3-6.8 is best... over fert or ph or both can cause the leaves to be curled under like that. The ferts in the soil are 14-11-8 , thats very high, i think u should stop giving extra nutes for now and transplant into a better, more ph balanced soil.

    They are getting too much nitrogen. Kick back on the ferts for a week or two and flush the pots the next time they need water.

    aye, i was starting to suspect too much N. they're lookin a little better, but now other discolorations are showin up. guess this is why i did my first grow with bagseed, eh?

    thanks for the tips, all!
