I've been getting these holes in my hygrohila Compacta and previousoy hygrohila 53b which I took out because it was too bad with no improvement. Compacta is still having this problem also with chlorosis and slow growth if any and both the 53b and Compacta has been dropping leafs alot. The new slow growth on Compacta seems better but still getting holes on older growth. Java fern and s repens are not affected. I EI dose, inject co² and achieve my 1ph drop and lime green drop checker. Flow is good everything moving and light is fluval 2.0 at 75% and a photoperiod 6.5hrs. To me it looks like pottasium defiency but I've tried doubling ei dose with no improvement also micros to try and combat the chlorosis. I'm wondering if it could be that sunlight hits the tank from morning and is messing with the photoperiod but then the s repens would have some I'll affect? Any help much appreciated.
