light is a 400 watt hps about 18 inches ( reccomended is about 12 but its a son t and it burns my hand from 12 inches)
been checking for bugs see none plus my other plant isnt affected..
Nything else i shoukld check?
i was thinking maybe n burn cause its been in flower for nearly 2 weeks and i still fed it with grow rather than bloom.. and in flower as we all know no need for excessive ammounts of n.
So im not sure maybe ph?

Bottom leaves get used up by plant then fall off
grow nutes first week is ok use bloom
make sure to look under leaves spider mites are real small
may have to water outer pot also don't really know...use little in each

Hey man .. yeah i water both outer and inner pot, just waterd bout an hour ago shes perking up now but these bottom leaves over night dying of has got me worried, its too early in the flowering i think for them to be getting used up by the plant, could it be not enough light reaches them?
Ive also checked under leaves but nothing not a single mite :)
 
Here we are, the big yellow leaf is the same one as on the pic from yesterday further up .. picture 3 is a part of a leaf that went crispy put it on the canopy so you can see how yellow it is :)2015-03-04 20.47.15.jpg2015-03-04 20.47.33.jpg 2015-03-04 20.48.36.jpg 2015-03-04 20.48.56.jpg

nah phd tap water 3 days setting time, Hmm i dont know where u see the tips curling up man , if ur thinking of the big yellow one i rested it on the edge of the pot for the pic otherwise it falls to the soil, by the way it feels saturated not dry at all then theres other ones that are completely dry..
 
Oh my fault I was skimming the threAd bc in at work so I probably misread it. I didn't see it I just thought I read that
 
I'v seen two plants in one pot gets root bound yours is the first time i'v seen one plant in two pots really don't know what's going to happen
plant rite now looks ok i'm worried about root rot or getting root bound still got 4/5 weeks to go

OK so heres why i did what i did, I planted the auto without knowing they shouldnt be transplanted, pot was only like 5 litres and i thought that would be too small so i increased it to bout 12 litres , i put a bunch of holes on the initial pot to give roots free passage.. i prolly should have just cut the bottom of the pot but i already planted it when i thought of this, anyways im a little worried on the rootbounding myself cause 2 days after i potted up i got roots at the bottom of the second pot thats bout 10cm difference between bottom and bottom, i dunno i just hope she pulls through ok although shes just in there to give me a quick smoke, ive got a cream caramel going alongside her right now going to veg it till auto is done cause shes a slow grower and well , i have the space to be honest so why not :D
