hey there, seems like your soil matrix got shocked by the tea and wasnt able to buffer the pH back down. That kinda burn on the leaf comes from pH fluctuations. You surely do want to be measuring that moving forward using pH strips or a pH meter. Both work fine ! you're aiming for 6.0 going in or pH 6.5 going out . You can probably cut out the alg a mic and the kalong in case you think the soil might get overloaded, compost tea will keep working for weeks to come and might "peak" in one week or 10 days' time so just keep that in mind. Hope this helps ! 🚀
