Hey Al, I did feel hesitant in asking you this but this issue is new & Im totally bamboozled so here we go:
Usually my clones look great apart from some yellowing which Im sure is standard but now the new set of leaves are beginning to crumble & wither they are also turning in to a slight pale yellowy green colour with dark brown blotches. I just dont know why. Here are the environment conditions & pics:
25C
80%rh min
Plain unPHed tap water with a little superthrive
2inches away from 2 x 18W fluorescents.
First planted the clones in rootriot then transferred to Biobizz soil (light mix) when roots showed, they are currently in the first day of veg. Id like for them to pick up in a week then theyll go in to flowering.
The same signs are showing on my other 2 batches of clones.
The below pics are larger clones which were cut on 16/07/09 which are also in Biobizz soil (light mix) but I thought Id try out these Jiffy pots, Ive heard by using these pots they can become root bound
so Ive transplanted in to larger black pots & the leaves are beginning to crumble just like the first batch
