How to airate soil? Lower PH
I have been growing plants from seed in 6 oz cups, i think i kept them in the cups 2 long, i have been late on watering a few times and it seems like my plants are not getting enough nutrients from the soil,, I am using a good soil fox farms. When i repotted to larger pot my soil was kind of hard and crusty, i dont think when i am watering the water is draining well, i think it just pours over the top and down the sides of the soil.
Also i want to lower my PH, i dont want to go crazy with lime or things like this, i am just looking for a home depot product i can easily use.
