Hi all,
I have a 80L tank that is running for the past 4 months. Although I didn't see issues with plant growth in the beginning, I am recently facing stunted new growth and white pale leaves in some plants.
Details about my tank:
KH: 3dkh
GH: 4dgh
ph :7.2 before CO2 and drops to around 6.1 after CO2 injection.
Substrate: Ada Amazonia version 2
Lighting: Chihiros wrgb2 for 6hrs daily from 4 p.m to 10 p.m running at 80 percent intensity and with a ramp up/down time of 1 hour.
Filtration : Eheim classic 350
CO2: Starts 2 hrs before lights on and off 1 the before lights off. 6bps via JBL inline diffuser.
Maintenance : Weekly 50 percent water.
change.
Fertilizer : 3ml of APT complete daily.
Rotala Shimoga leaves turning white:
Ludiwigia glandulosa with stunted curved new leaves
Rotala macrandra mini butterfly stunted tops:
Rotala wallichi stunted top
Overall tank pic (taken a week back)
I see much of the cases of stunted growth has been associated with CO2, but I have my drop checker turn to a good lime green 3 hrs after CO2 is on. I am suspecting this to be iron deficiency but not sure why this is not seen with other folks who use APT complete. Perhaps the time of dosing ferts play a role? I dose in the morning and go to work (9.am), while the photo period starts sometime in the evening(4 p.m). I did read in some websites that the DTPA iron would precipitate if the ph is above 7. Does this have a role to play in the stunted growth.
Any help on this is greatly appreciated.
Thanks in advance. Love from India!

Vigneswaran
