Hello everyone. I just joined this forum and am pretty new to planted tanks. I have been keeping fish for about 12 years now. My first setup was a 10g with DIY co2 and has been doing great for about 2 months now. I just started a new tank, a 75g. My substrate is fluorite mixed with turface topped with sand. I'm running 2x2T8 fixtures with polished aluminum parabolic reflectors. Each bulb is ODNOx2 which gives me a little over 3.4wpg (T12 equivalent) or 16000 lumens. The bulbs are 2 x 5000k Philips and 2x8000k AGA. I'm running pressurized co2 at 3bps. My drop checker has a 4dkh solution so I have about 30ppm co2 in the tank. I will be dosing EI. Now that we have the tank setup out of the way, on to my question. I just planted everyone on Wednesday, and everything seems to be doing alright so far (the crypts, anubias, and Alternanthera Reineckii Var. Roseafolia were even pearling today). The only exception is the HC. It came in green and beautiful but today it looked like 60-80% of each planted bunch had melted. Below will be a picture of how they look. I plan to make this a discus tank, but my discus won't be in until this coming Tuesday so I have not raised the temp yet. It sits at 82 during the day and 80 at nights after the lights are off. Any info you guys can provide on what's happening and/or what I can do about it would be greatly appreciated. Let me know if you need any more info on my setup. Thank you all in advance.

Here is a picture of what the bunches look like.

If the Hemianthus Callitrichoides was just planted and everyone esls seems happy, best guess is the were grown emersed and are adjusting to life, submerged.

I would trim anything dead, give it a little time and the little guy should take off.
