    Hi guys, me again, the Doc.

    I've noticed that my plant's leaves are curling down and under themselves. Also I have a couple of leaves that have holes in them, but I don't see any insects, etc. There are also yellowish splotches on some of the leaves as well. It's been a week since I've fertilized the plants. I know that I should have pictures, but my camera's broken, I'll post some tomorrow night. Any clues?

    Thanks!

    pH is really important.... You need to get yourself a digital pH pen....$40 for an inexpensive one....and some pH up & down, about $20 for both.... Correct your pH and then let us know how they look.... Also, when in doubt, flush it out.... As long as you don't have auto release nutrients in your soil, you should be able to flush out built up salts/nutrients with a couple flushes.... Use 2 - 3 time the amount of water your soil container holds to flush with.... Let soil almost dry before watering or flushing again....

    Start with pH....

    I have taken some pics. I hope that the 2 minutes of light that the ladies received won't do any harm. They're in their dark period right now.

    The below pic is of the two ladies. They are into their 2nd week of flowering as of today.

    lol 1st you shouldn't interrupt the night cycle

    as for curled tips?? after searching for about 10 seconds i've found it, and CanGroIt diagnossed it with ph problems

    ok, thanks! since I don't have a soil ph meter, should I water the ladies and measure the PH of the water that comes out from the drainage?

    how long have you had the plant? you said you dont have access to nutrients, but the person who was growing it before you did, and probably over did it/didn't balance the ph?? I also do not have a ph meter but my plants seem to be doing alright, even with feeding them miracle grow tomato food and schultz cactus fertilizer

    my hopefully female plants were given to me when they were about a week old. I've vegged them from end of may to July 30th. Now they're up in the flowering area (it's been 2 weeks today). Up until now I've not had any problems. I most likely over ferted because last week I fertilized and they started with this recently. I got some more pics if you'd like to see:

    the first 2 pics, are they the sex of the plants? or are they the thingy that becomes leaves?
