Types of Deficiencies

Before you get started make sure your to check PH levels this is one thing that scan cause many deficiencies and problems!

The optimum pH in soil is around 6.0 – 6.8 and the optimum pH for marijuana in soilless or hydro is around 5.5 – 6.5. If you grow in a soilless medium like coco, but with added organic matter (worm castings for example), you should consider aiming for a pH value somewhere between soil and hydro. Remember though, you are looking for a pH range rather than an actual number.
