Hi all I am trying my hand at growing marijuana for the first time. I have one Durban Poison plant growing in a 55 ltd pot and it has been growing very well so far. It is from what I can make of it in the fourth week of flowering with a some but not excessive yellowing leaves and is also not growing any higher at this moment in time. From what I've read it is normal for it to slow in growth for the first four weeks of flowering and then it starts to take off again is this correct. I fed it a small handful of fertiliser with nitrogen tonite and also have been feeding it with every watering a bloom enhancer called Bio Diesel which on the instructions says that you need to start adding it to your water when the flowering reaches the first week of the bloom stage. Bio Diesel is high in Phosphorous. Have I added this to early, I am am adding it to the water at the lowest amount stated on the container. The plant looks healthy other than some yellowing leaves as stated, I am beginning to worry a bit that it has not started growing anymore and and that it is not filling out. Any advice would be appreciated.
