Approx. 15 weeks old, my girl has purpling leaves. it doesn't really look bad, but this morning there was a little brown crisping on a few edges that wasn't there when they turned purple. i'm not sure they're supposed to be purple anyway, just lookin for some feedback. if something isnt right i would like to know how to fix it.
i put her into 12/12 kinda early. at about 7-8 weeks and she was only a few inches tall. she grew rapidly and then slowed down. shes not much taller, but started producing flower.
i don't have any pics at this time, but i may be able to take some if necessary. could this be temperature issue combined with ph inaccuracy?
