First feeding between Week 2 and Week 3.

Start with a weak veg food 1/4 strength or less.. Easier to increase then decrease or high nitro tea. However you must consider your starting soil. If your soil has food in it then do not feed them. depending on what is in it. You may not need to feed till near the end of veg.. Then just plan water when there dry. Try not to over water it will kill the plant faster then under watering. Its also advised to keep humidity up however as you can see its not needed. 14% humidity. It should be noted that at anything less then 40% humidity. Spider mites will become an issue. If your plants are staying inside they need better humidity or prevention. Anything over 70% humidity without airflow/cleaning and everything will mold. So 10% humidity can be sprayed with water or a humidifier applied to room. 60% humidity should be left alone. 75% or higher should be lowered and air cleaned often.
