I dose ADA fertz: Special Light, Brighty K and ADA Step-2 for the micro's.
Dosage is daily 2 pumps each, (2ml on 40 liter = recomended)
Testing gives the following results:
Fe - 0.5
NO2 - 0.1
NO3 - 4
PO4 - 5
K - 25
CO2 - 30 ppm
KH - 5.5
(50 liters - Tropica soil powder - good flow and no algea -
Scaper Light 1440 Lumen lights voor 8 hours)
Plant growth is very wealthy but there are some defficiens I think. But as you've noticed the PO4 is way to much?
Leaves are starting to become yellow and the edges of new leaves start to get brown,
the older ones get dark. (those tiny spots is soil/dust - no pins)
Any advice?
