You got no fish in there or inverts right? Crank that CO2 up. It can help maintain good levels so HC can transition better. Make sure you have a decent flow on the HC. But melting screams CO2 issue.
Also, you might think about switching lights to 6500ks. 8000k will work but its not going to deliver useable energy as efficiently as the 6500k's as they provide more light within the 400-700 nm range. HC will need medium lighting to grow nicely. I use on my 10 gallon a cheapo odyssea 2x18W T5HO you can find it on amazon for plants. Works fine, though I have it raised a bit higher since the light was too high I could not support the CO2/O2 levels necessary.
Follow EI or some kind of dosing regime if you can, then its all about CO2. IMO work load is like 1% light, 2% ferts, 97% CO2.
P.S. Dry start the HC! Will help em root better! Also, 0 algae.
