Hi everyone !
i was away this week, so i full the 2 tanks before i leave, and ask to the room mate to adjust pH each day and add only tap water when the level drop.
when i come back home again, some leaves turn brown and dry on the edge 😢 and the leaves are all curled down.
i don't know if it's due to overdose, pH fluctuation, etc ...
Do you have any ideas guys ?
Edit : I bet on Mg carrency
