Golden stains on the leaves (new grow) Please help!

Hello,

We've on our 8th day and today some golden stains appeared on some of the leaves.

What is it? what should we do?

Help please!
Thanks

I feed them with Cannazym. could that be the problem, or is Not feeding them a problem?

I'm clueless here... and worried of course.

Start by doing the easy and less stress option- FLUSH; no nutes until they get a lil bigger, When they get big you can use lots of nutes so slow down, relax.
Good luck- I think she will be fine though.

Thanks! Will refill the tank with fresh, new water tomorrow.

Though... there's just one more issue with one of my other plants: it's leaves started closing into themselves (attached another image).

Any idea what's causing this?

Going to do so ASAP. I sure hope it's the nutes, i'll need to buy loads of fresh water tomorrow

Thanks for all your help! :]
