I've had small clusters of DHG planted in my 10g tank for at least of month and I've only noticed negative progress. Many of the leaves turned pale and disintegrated. However, there are still small clusters remaining in the substrate, but there has been little to no progress in terms of growth (let alone carpeting).
-Substrate = ecocomplete planted substrate
-Lighting = 2x 24 watts 6500k t5 (suspended 6 inches above tank)
-C02 = DIY setup (microfilter used for dispersion)
-Ferts = Weekly dose of flourish, flourish nitrogen, flourish phosphorus, & flourish potassium (The LFS told me i may be lacking in N, P, or K)
-Water parameters = ph[7.0], ammonia[0-0.2ppm]
-Livestock = 1 dwarf gourami, 4 cardinal tetras, 1 nerite snail
All the other plants are doing really well and hardly shade any of the DHG so what the heck is the problem????
Attached is a photo of the tank in question. Any feedback/info is much appreciated.
