Hello.
I have 3 plant in my tank with strange signs of deficiency which I can not determinate.
First about tank
300 l
Lights - 0.83w/l - 10 hours day
KH-2 GH 7 (Ca-21mg/l Mg -9-12mg/l)
CO2- from CO2 tank with reactor after filter outlet. Controlled by Ph controller (maintaining Ph6) DC - always yellow
Filtration FluvalFX5+Atman CF1200 (just for CO2 dissolving)
Ferts. Dayly Dosing: NPK+Micro+Fe
Approx concentration in water (K-20, NO3-20, PO4-1, Fe 0.3-0,5)
Micro
Mn 0,0253
B 0,0019
Cu 0,0014
Zn 0,0043
Mo 0,0005
WC-1times per week 50%
1. Ranunculus inundatus.(pic1) It seems to grows well, gets new leaves but it has very strange color, you see it on picture - its not a mold - i check - the stem is quite consistent - any proposition?
2. Micrantemum umbrosum. Here is more bad thinks. Actually its appeared on young leaves and on apical points. Some stems good some not... This plant was transferred from another tanks. Firstly i thought that plant adapted to new environment - but its already 3 weeks in my tank.
A have only one estimates - may be its Boron deficiency - cause my Boron dosing is less then typically recommended. But from another side -all others plants (R,rotundifolia, E.stellata, H.microntemoides etc noth shows such symptoms)
3. Microsorum pteropus - narrow leaf.
Some leaves-end of this plant became very faded. Its like chlorosis but.. it can not be according to my ferts dosing. One leaves pale others have dark green color. I thought that this is due to bright light - cause he planted in bright zone. But people told me this its not a light - any suggestion?
