Hey Kanni, nice to see you mate.
It's a 20l pot and I get about 500ml of run off from 3l.
Ph question, I watered last night with plain water with molasses. The ph was 7 and as I'm hoping the soil will buffer I did not adjust it. The run off was also 7. So my soil ph is a little high, although the new growth is great and not showing any signs of dislike for the soil. So here's the question, what can I top dress the soil with that's going to lower the ph without upsetting the balance of the soil?
