lol sounds like my first grow...heres my advice for guerilla grows...must be somewhere close to you and where it wont look weird to bring water and nutes and stuff, should veg a plant for about 3 weeks indoors before the outdoor season starts, do not plant too close to water like a creek bed because a month later that creek may have risen and boom your plants under water or it rains and your soil erodes away exposing roots...just dont plant too close to water..i would buy some blood bone meal and mix it in with dirt till up the ground well and mix the blood/bone meal in and then take the soil you made and mound it up the main cola removing the bottom node if its small branches then continue to do this as the plant grows always top dressing. thats how i do it outdoors anwyay...guerilla grows are hard, mentally i mean, almost not worth it imo especially when your legal anyway may as well find a legit place indoors or on private land.
