is pearling very hard to grow?

[RockBaby]

i try to grow my pearling but the leaves like turning yellow.
i use DIY CO2.. light use dymax robot light

[Fuzzy]

The Dymax robot light is far too weak for any plants that require CO2 to be able to effectively utilize the CO2.

You should consider upgrading the lights, or stopping the CO2 injection for now.

ok. i shall stop my co2.

[RockBaby]

thanks for your advice

No problem, and I'm guessing by Pearling you are referring to Glossostigma Elatinoides?
If so you might have a rocky road in front of you, this plant does best with very high lighting levels..
