Plant Problems
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.
second big issue is to note your temps, are they running over 80F or ( 27c ) if so you may want to check into running co2 but could become costly and or a waste if time if your not running a sealed room.
are you over or under watering? even though plants may be the same species doesnt ment they intake and put out the same. the best way to go amongst this is to know the weight of your pot both dry and wet, note where on that scale your plant likes.
