yes, when the leaf tips are curled down like that it is usually a sign you over-watered
You really need to get a way to test your pH. Even if it’s just litmus paper strips. You cannot “guess” pH your plant is locked out and not getting any nutes. Using soil again will also mess with the pHA whole butt load and every 15 minutes… LOL. This is reused soil. Last time I reuse some of the same type it was light and fluffy this time it just seems to be compressed and waterlogged. As for PH I have no way to measure so I put in a little bit of the MC and a couple of drops of white vinegar. My tapwater in its natural state is about 8.0
