This pattern eventually turns the whole plant brown. Rest of the tank is thriving. What do you think this could be?
I am guessing your ammonia is too high. I had the same issue with my tank, but waited too long. All you can do is save the plants that aren't dead, and definately do at least a 50% water change.
Ok I haven’t done a water change since I set it up, prolly gonna do one now then.
What's ur ph and kh at now? Might just prefer less acidic water
I have a heavily planted tank that I almost nuked because I wasn't doing water changes, just topping it off because the nitrate always read 0. I'm going to guess KH is high and water is closer to brackish/salt ph
Was 7.3 ph, now 6.8. Consistent KH 2 ,0 Ammonia , 0 Nitrate & Nitrite. Ig yea the PH was too basic, and buildup of some minerals.
You’ve never done a water change? How long has this tank been setup?
Set it up about 2 months ago, fixed the problem by doing 2 30% water changes. Water tested perfect at my LFS, tank is great now. I also have aphids on top so that sucks.
