Hello Schorsch,.
8-8-6 is not necessarily a sumptuous meal for konjac in comparison with the also mentioned blue grit.
(Blue grain is also not blue corn, that there are from different manufacturers in various Zusammensetztung, for example 12-12-17-2, 12-16-3-10, 15-3-20-3-10, 21-5-10-6-3, N-P2o5-K2O-MgO-S (respektiv))
I would keep me in your Flüpssigdünger on the dosage instructions, but with the double concentration you're doing wrong nothing in konjac safely.
Molybdenum is important in the conversion of nitrate nitrogen to ammonium in the plant; If it is in terms of defects, it comes to non-specific Chloroses (green yellow leaves), especially with Kohl to deformed leaves.

Your master gardener takes not necessarily little with 14 to 22 g / 10 L, so 0.14 to 0.22% at a daily irrigation fertilization, but you can fertilize eg Phalaenopsis orchids with 0.07% of Orchid nährsalzes for each casting. Your gardener would make sure very quickly that if the Margarithenbüsche would not contract.
I had always full of praise, if at all fertilized is...;-)
Happy fertilizing, Bernhard.
