what locks out n2
i'm growing out three new phenos
using GH nutes modified lucas 6-9, in coco, in party cups, 12/12 from seed
i've stepped up the ppm from the very beginning, but always using the 6-9 ratio vs. the GH recommendation.
In the coco, I am now using 6ml/gal micro and 9ml/gal bloom which gives the nute profile:
N 97
P 60
K 105
Mg 41
S 27
Ca 97
to which i add some cal/mag+
almost from the beginning i've observed lower leaf yellowing, sometimes under-curling, the top growth appears very active.
i'm thinking i have a n2 lockout, and i don't want to just spuriously add some n2 to the mix, which would be my gut reaction.
i was wondering, if certain elements would tend to lock-out n2 and reduce them vs. adding n2
but i am at a loss.. other than pH issues i don't see where the formula above won't work.
i pH every watering at 5.9-6.0, but mixing in volume i've see ph rise and fall, sometimes dramatically, between waterings, i still pH each batch...
the plants have had some unneeded stress, high ambient heat, inconsistent light phase, etc.. currently i'm currently growing 12/12 in a party cup.. blah, blah, blah..
what i'm asking i guess is, what do you think the lower leaf yellowing is due to?
n2 lock out? how to cure?
pH problems obviously... set your watering pH at...?
don't panic..
dude you're fuked.. sell me your plants...
