yeah i repotted it in a smaller container and left it near the light it lasted for ages untill i decided to give it a lil sun,then fried the poor basterd....
it think it would add to the smell and the weight in the long run,try molasses,
but really dude i wouldnt bother the plant wont start using the shit cause its so late into flowerring,its pointless
umm dude im stoned so i aint reading all that u just wrote..
but in the second photo it looks like u ave about 16 plants in one tub,correct me if im rong...
The only reason to my knowledge u should spray the foilage is when the ph of the soil is to low caused by the large amounts of fertilizer's used.
The soil builds up with salts causing it to be more (acidic)
use very diluted fertilizers when spraying the foiliage,
