Seed stuck on the plant

I agree with everything @GrowCN has said.... follow his advice!!!

Do not do anything. The plant will take care of itself. By trying to help you have a very real risk of damaging the sprout at a very sensitive time in it's life. As the plant grows it will push it off naturally, plus you've already got true leaves so the cotyledon (false, first leaves) leaves are going to whiter and die anyhow. Remember, no plant in nature has a human come along and remove the seed husk.

Its the membrane stuck, Keep it wet and it will eventually slip off. Try to only get it wet and not the true leaves to avoid any kind of burn from the light. You have your true leaves out and that is what matters.

it does however look like a membrane from the seed is still clinging to the leaves. keeping that moist or cutting it, accurately, with a VERY sharp knife should release them into the light.

I use a pair of tweezers to pull off the shell. Just make sure you grab only the shell and pull very gently. It should slide right off. Good luck!

leave it alone, it will fall off.
