So theres about a month worth of pictures in here. Ill doa bit of a narrative.. Dec15- everything was fine.. maybe lacking a bit of color. One or two yellow leafs. Was giving it normal veg still or preflowering, dont remember. Still heavy on N. Jan05- Problems couldnt be ignored, so i began thinking what could it be, thought the mix was too strong and coco had salt build up. ( not sure about tht anymore) Jan 7- we've flushed. Jan 11- we intruducrd a light dosage of preflowering mix, at 1100 ppm.( full is at 1800). Yellowing might have not progressed, but affected leafs degraded fast. Jan17- we gave it a bit more nuts, still preflowering mix, at 1600 ppm. There aint many more affected leafs, so she lost many solar panels :( smaller leafs are either unaffected at all or have a clawing to it, specially near buds, seems nitrogen tox to me? We will see in 3 days how things have developed when i update this diary... hopefully xD So all this was either N tox, or N deficiency xD Any thoughts are appreciated ;)
