Yellow leaves on autoflowers

  1. These autoflowers are about a month old. Everything was going fine up until about a week ago. I noticed the bottom leaves are starting to get a little yellow and I'm assuming it's because of the ph balance. I bought a ph tester but it's not working properly so I plan on getting another one but just out of curiosity I'm wondering if anyone can tell me exactly why the leaves are turning yellow and what I can do. If It's because the ph balance is too high or too low. Hoping to cure this problem before they get completely ruined. Please help :) thanks!
