ok so some leaves are turning yellow as but too far gone b4 i corrected the problem? can i just cut the leaf off ? or let em fall of naturaly .....of course its better naturaly but im just curious will it cause the plant too much harm? oh aslo there about 2 n a half weeks old ...cheers
Any leaf that is still fresh (not dry) and is green, even if partially so, will take part in photosynthesis.
I would advise leaving them unless they are dead, in which case they would fall off naturally.
give them a light tug and if they dont come off try again in a few days. i lose a bit of bottom leaves once my conapy expands due to the light just not reaching them. if they dont come off with a light tug the plant is still moving nutrients out of them to other parts.
