First time

If you do not have a lot of money, then stick with a 2 part nutrient combo, it will have you covered from seedlings to harvest. There are way too many companies to go through, so just take a look online to see what is available in your area. If you have access to Gaia Green nutrients, take a look at those. Its an organic slow release fertilizer and dry amendments. Their All Purpose is a 4-4-4 NPK, and the Bloom is 2-8-4. The last number, potassium (K) is what you are needing to fatten up and harden your buds. For that, you need a bud or bloom booster, which is quite often just a huge dosage of PK or just straight K. I myself will be trying out some of Green Planets -Dense formula, its just 0-0-62, so that should be a kick start to some "dense" nugs. Happy Growing
