Growth of wallichii stunts after a while at the tip (smaller and smaller leaves until growth stops) and produces new shoots lower down. This happens in about 50% of the stems at any one time. Coloration is good though (pink in daytime and red for last two hours of photoperiod.)

Tank Specs:
Size: 38 gallon

Lighting:
96 W CF @ 7 hours (in back...Rotala in back), 39 W T5 HO @ 2 hours (in front)

Fitration: Eheim Ecco (can't remember model no) and Rena XP3

CO2: pressurized....30 ppm as per drop checker. Turned off at night and 1 hour before lights one.

Substrate: Fluorite

Fertilization: EI
1/2 tsp KNO3 Sunday, Tuesday, Thursday
1/8 tsp KH2PO4 Sunday, Tuesday, Thursday
1/8 tsp TE (Plantex CSM+B) Monday, Wednesday, Friday
20 ppm Calcium (Calcium Chloride) and 5 ppm Magnesium (MgSO4) added once a week at 50% water change on Sunday

Any ideas on how to fix the stunting issue?

R. wallichii seems to do slightly better when I cut back some of the other plants, but I don't think this is entirely the problem. Any ideas?

No ideas Im sorry I did really well with it for months then it started doing same and I tore it all out... If you can get a new portion I would try that as I dont think this stem plant is as resilient to trimming as others... But as I said I gave up when it stayed crappy for weeks when previously it had done well....

Yeah I'm on the verge of tearing it out myself lol.

It did exactly the same thing in my low-tech 72 gallon too. Perhaps you're right about the constant trimming. Too bad because its such a beautiful plant.
