Hi everyone, I'm a novice grower. I didnt add any perlite or anything like it the soil. My soils drainage is low, and ph is around 7. I ve learned a good lesson about how important the soil is. I ve heard about humic acid. Can I use the humic acid to lower the soil ph and to increase root system and make up for the mistakes I did ? Or is there anything I can do at this point ? And is it ok to us humic acid when the plant is flowering ? Thank you
