Plants Turning Black In A New Tank

HI All

I recently set up my new 125 gallon tank with plants. It has a bunch of Rotala and Jungle Vals. Rotalas are doing fine but the jungle vals are kind of turning black. I have used baked garden soil as substrate with sand capping. Used garden soil before and it worked fine. No co2 and fertilizer. 60w of led lights with 7000lumens. What am I doing wrong?

 

Pics please?

Thanks so much. Please enlighten me if you can.

 

There probably isn't enough nutrients in the water, have you tried dosing with liquid fertilizers?

Well, I haven't as I was told that jungle val is one of the most non demanding aquarium plants. I have had jungle val before, even in of the tanks where there was only gravels and I had difficulties managing them as they were actually spreading runners everywhere. However, is it possible that as my tank is only a few days old and going under the cycling process, causing plants melting? I will use some liquid ferts too. Thanks

 

Cycling a tank shouldn't damage plants, but there is probably a lack of nutrients in the water, that or your lighting isn't good enough.

Ok. I will try some ferts first, then look into the lighting. Thanks so much

 

No problem. Good luck!

Umm just curious that black growing 9n the plants could that be a black hair alge? If so if Alge is growing it would be Indicting the water would have more then enough nutrients. That the alge would be taking the excess which leads to starving your plants out.

 

If the alge was to take over

Hey. Thanks so much for asking. In fact, things are falling into places. I spoke to the seller and he said these plants were grown not submerged but immersed ( only roots in water ). These immersed plants generally tend to melt initially once they're put in a tank ( quiet an insight for me) . I am already getting some new leaves.
