i'm using project soil and light wise is T5 2x24W (1 tube is 12000k the other is 7500k) on for 11-12hrs a day.
Hi ciaossu,

For HC, I get melting whenever the leaves are too wet (touching water). Thus I try to keep the soil moist rather than wet and this may be your issue. Another possible cause I can think of is transitioning from submerged to emerged state, but most local sources of HC are in emerged state to begin with.

Once clumps of leaves have melted, it helps to remove the clumps as otherwise, the rotting mess may cause secondary issues like fungus or cyanobacteria.

I don't think your lighting is an issue.
