Soil: all mix plus little cocco+perlite extra (15-25%)

fert: biobizz starter pack (grow,bloom and topmax) I use them only after 23days (start flowering). i start with low low dose of (1/4ml of each ) second was 1/3 ml of each, next was 1/2ml and then the last two was 1ml biogrow, 2ml biobloom and 2,5 ml fo top max (full dosage of schedule)

pot: 11l modded -> the real should be 4,5l-5l with a good drain at the bottom due to Expanded clay 8http://cdn4.http://www.greenstyle.it/wp-content/...la_espansa.jpg)

Temp and ur: all good since the very beginning 18-24 in veg and 20-16 in flo ur 50%

water: from a local supermarket, bottled water with 6,8-6,9 ph. If my ph meter works the drain water in the bottom is 6.75 yesterday, seem good.

[/FONT][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif]So all was good till 10 day ago-> yellowing and leaves death from bottom to all plant.
Today the situation was critial, and i realized she ll die, the flowering is stopped for sure and the all leaves are whit browm.
I take the plant outside the pot and find the problem: the roots have had colonized all the soil and the pit under it(it drain the water, but roots have blocked this), and most of them are brown, absolutely not with. So i cut all the part of the roots the are rot and repot in bigger pot, with new soil. The problem is that thew flow is start 25 days ago, and now the plant haas half root. Does she will survive?

the yesterday the situation is resume in my photos in this post
